Re: Fuseki errors with concurrent requests
Hi,
unfortunately I haven't been able to make a standalone package yet.
However with jena 3.7.0 things are bit better now - errors occur less
than before.
Actually now I'm not getting error codes from Fuseki (all 200), but
errors still occur and at that time there is Fuseki output
TransactionManager ERROR There are now active transactions
This occurs when Im inserting new data and trying to read it right away
(get empty result), or deleting data and trying to read it to make sure
it's deleted (get data that should be deleted). There are no other
errors in the log.
Is this because things are happening too fast, in kind of artificial
bombing of the service? So just slowing things down a bit would solve this?

Re: TransactionManager ERROR There are now active transactions
Posted by Dan Pritts <da...@umich.edu>.
I haven't been following this thread closely, but if you need to log
POST (and all other) contents of an HTTP stream, and the application
can't log it for you, there are two approaches I'd recommend.
1) sniff the wire. If you aren't using TLS, this is trivial. If you
are using TLS, it may still be possible.
https://wiki.wireshark.org/SSL
2) apache mod_logio. This assumes apache as a proxy in front of
fuseki. The logs are ugly, but it's possible.
3) there are other proxy packages designed to work as a
man-in-the-middle for just this purpose. I haven't used any of them
very much, I have notes pointing out these three:

Im switching to another project so we won't be able to look at this in

Re: TransactionManager ERROR There are now active transactions
Posted by Andy Seaborne <an...@apache.org>.
It's a not insignificant amount of work to pick the 310 recorded
operations (150 updates, 150 queries, 10 GSP operations), write a script
on invoke them, and set up a simulator for your environment.
Then, maybe, it will cause show the log message. Or maybe not, because
of all the different machinery. Maybe it is something to do with
connection patterns.

Re: TransactionManager ERROR There are now active transactions
Posted by Mikael Pesonen <mi...@lingsoft.fi>.
This was just an example, here is the test set with instructions:
https://www.dropbox.com/s/r1fd48v62822u2n/How%20to%20use%20the%20Public%20folder.txt?dl=0
Just after fresh start of Fuseki, this error is harder to cause. After
running in low/normal load for couple of weeks, it occurs easily in
every test.
So right after restart of Fuseki, only way to cause this is to repeat
the query set in 10 (for example) concurrent scripts until the errors
occur. Ive usually got it in first 50 rounds. Of course this more load
than in real production but just to speed things up.
And there are 2 kinds of ways this "TransactionManager ERROR There are
now active transactions" occurs: transactions are succesfull or they are
not. Running this query set doesn't of course tell which ones they are.
I did tests in empty disk based TDB1 and fuseki 3.7.0.
Regarding to in-memory tdb, actually Im not sure if it works or not,
since I didn't do very long tests there.
Also while running the test, I got seemingly random exceptions. Here's one:
org.apache.jena.query.QueryException: Secondary index duplicate:
GSPO->GPOS -> [[0000000000000000], [00000000000EF6D7],

Re: TransactionManager ERROR There are now active transactions
Posted by Andy Seaborne <an...@apache.org>.
Mikael,
So if the 62 operations in this log are executed on a server starting
with an empty TDB1 database, it will show the error? Every time such a
test is run or only sometimes? The same place in the sequence of
operations every time?

Re: TransactionManager ERROR There are now active transactions
Posted by Andy Seaborne <an...@apache.org>.
We need to recreate it with a debugger attached.
If you could collect the HTTP requests the scripts are making, then with
a copy of the data, it might be possible to recreate the situation.
Otherwise it's "something happened". I can't see how to recreate it
without a use case.

Re: TransactionManager ERROR There are now active transactions
Posted by Mikael Pesonen <mi...@lingsoft.fi>.
With in-memory db everything works. Ran ~50000 operations x10 (10
scripts in parallel) and no problems. Mem usage was 3g-5,5g (java
xmx4000) and vm 10g.
So what does this tell? System is upcloud server so there shouldn't be
any issues with disk there...

Re: TransactionManager ERROR There are now active transactions
Posted by ajs6f <aj...@apache.org>.
That seems a bit strange. I would think that the single dataset lock and multiple-reader-or-single-writer policy would guard against this-- only one thread (request) can mutate the dataset at a time. Or is this a problem with TDB? Do you see this occurring with in-memory datasets?

Re: TransactionManager ERROR There are now active transactions
Posted by Mikael Pesonen <mi...@lingsoft.fi>.
Easier fix that sleeping was to add system wide semaphore which puts all
concurrent requests to single queue.
So the problem is in the way how Fuseki handles situation where
(concurrent) requests are coming in faster that it can process it.
Usually there are 2 ways to handle that: return error to client or sleep
until there is more space in request queue.

Re: TransactionManager ERROR There are now active transactions
Posted by Mikael Pesonen <mi...@lingsoft.fi>.
I dont have any configuration, so it's default?
Command line:
/usr/bin/java -Dlog4j.configuration=file:...log4j.properties -Xmx5600M
-jar fuseki-server.jar --update --port 3030 --loc=...jena_data_test/ /ds
log4j.properties is default except couple of INFO -> WARN

Re: TransactionManager ERROR There are now active transactions
Posted by Mikael Pesonen <mi...@lingsoft.fi>.
It does happen in our test environment on high load quite often. More
sleep I put in the test script, less frequently error happens.
Most of the time transactions are executed after the error, but not
always. Fuseki never returns error. Rarely below error happens, don't
know if it's related.
I'm not able to produce a sendable script that would case these errors.
So as a fix I'm planning just to add enough sleep between every Fuseki
call. 50-100ms seems to work.

No - it's an internal consistency check.
Does the transaction still happen?
Do you have a reproducible script to make this happen? I've never seen
it occur.

Hi,
is it somehow possible to get this error (TransactionManager ERROR There
are now active transactions ) from Fuseki GSP so that client could sleep
and retry later allowing db to finish the transaction?

unfortunately it's the same problem as before, we are testing with our
REST API product which if quite a bit of code and and I dont have time
to build a similar test case from scratch.

From looking at the code, I can't see how that happens - is it now
possible to provide a reproducible script so that I can run it on machine?

TransactionManager ERROR There are now active transactions
This occurs when Im inserting new data and trying to read it right away
(get empty result), or deleting data and trying to read it to make sure
it's deleted (get data that should be deleted). There are no other
errors in the log.

Yes, made a dump and imported it with tdbloader2 into empty jena data
folder.

"The errors" are which exactly? the thread doesn't make it clear.

The only code paths that lead to this I can find are either inside an
exclusive lock or StoreConnection.expel, which is a somewhat drastic
thing to do and the app needs to make sure it is quiet first.

When an HTTP request returns the transaction should be committed and
visible. Calling in parallel
Remind me again - what's your setup? OS, hardware and Fuseki configuration.

It is worth trying to see what the effect is, though it should work.
