subversion 1.7 - Internal server error (HTTP 500) - user account gets
locked out
Hi Team,
We are using subversion 1.7 version and we are facing issues very often
when the users trying to commit or checkout they are getting HTTP 500 error
and the user is getting locked out. The users are authenticated via LDAP.
At first we thought it was a server resource crunch issue and we increased
the server resources but still we are getting the same problem
Here is the current details
Subversion running on single server
Repos : 135
Disk Used : Around 500GB
CPU : 4
RAM : 24
Subversion Repo file system type : FSFS
Below is the apache settings
Timeout 60
KeepAlive Off
MaxKeepAliveRequests 100
KeepAliveTimeout 15
<IfModule prefork.c>
StartServers 8
MinSpareServers 5
MaxSpareServers 20
ServerLimit 256
MaxClients 256
MaxRequestsPerChild 4000
</IfModule>
<IfModule worker.c>
StartServers 4
MaxClients 300
MinSpareThreads 25
MaxSpareThreads 75
ThreadsPerChild 25
MaxRequestsPerChild 0
</IfModule>
We have around 100+ users accessing the repos and the CPU utilization is
normal as checked in sar report.
Any advice on the same.
Thanks & regards,
Jackson J

I would suggest taking a look at the Apache error.log once you do as
it will grow very fast. The LDAP module logs a fair amount and
sometimes you get a sense where it is failing from the debug logs. If
it is possible to just put that module in debug logging it might help
keep the log size manageable.
It is probably mod_authnz_ldap (or whatever it is called) that is most relevant.

If you are getting a 500 then often there will be something logged in
the Apache error log, it might be helpful to see what error, if any is
logged. If the errors are predictable and reproducible then setting
Apache to log DEBUG can also help. This logs a lot though so it is
only useful if the errors can be reproduced easily in a short amount
of time.
On the server, Subversion is not really involved in the authentication
process. That is all handled by Apache and in this case the LDAP
modules. The Apache httpd version will probably be more relevant than
the Subversion version for fixes to these problems. I can recall a few
problems where setting LDAPTimeout to a low value like 5-10 seconds
can fix some problems. I do not remember these resulting in 500 errors
though, I seem they were more hung connections.
Maybe if something is logged in error.log it could lead to some
solutions. From what you have provided so far though, it sounds like
the solutions would be in Apache httpd fixes more than it would be
Subversion.

Hi Nathan,
Yes, we are building a new subversion server with version 1.10.
We have been facing this issue for the past 3-4 months and Meanwhile, is
there any performance tuning that can be done to fix this issue till the
migration is completed ?
Thanks & Regards,
Jackson J

Hello,
Is this an issue that has begun recently or has this been an ongoing
problem for a long time?
I would like to point out that the 1.7 release line is somewhat old
and has not been updated since late 2015. That by itself doesn't mean
it is the cause of these issues, but if feasible it is probably a good
idea to update to one of the currently supported release lines; the
latest releases are 1.10.7 and 1.14.1.
Thanks,
Nathan
