Solr 4.3 Master/Slave Issues
We have set up solr 4.3 with master/setup and are facing a couple of issues,
Index locking, the index on slave hangs at time and when we restart the core the core get's locked up. I have checked the logs and there are no OOM error or anything else other than the error given below,Caused by: org.apache.solr.common.SolrException: Index locked for write for core XXX

thanks Erick.
My tomcat setup is running on Ubuntu and has nothing else deployed other than the Solr war. My suspicion is it takes a long time to de-allocate the memory it has reserved for itself, but will get dump to find better.

Re: Solr 4.3 Master/Slave Issues
Posted by Erick Erickson <er...@gmail.com>.
kill -9 is evil, you aren't certain what the state is afterwards,
so the presence of the lock file is not surprising..
solrconfig.xml has a commented-out entry
<unlockOnStartup>false</unlockOnStartup>
I haven't personally used it, but it looks like it might
help if you insist on kill -9.
Personally I'd try to figure out why your setup takes
so long to shut down, I know lots of Tomcat installations
that seem to function so this might point to something
else in your setup that needs fixing.

RE: Solr 4.3 Master/Slave Issues
Posted by Cool Techi <co...@outlook.com>.
The normal tomcat shutdown doesn't stop the server and take a long time, so i do issue a kill -9 command. Any other suggestion to do this without the locking.
I would initiate a backup again and send the logs.

How are you killing the process? A SIGKILL will leave a lock file.

Just to confirm, are you using the backup command of replication
handler? Can you post a thread dump of the process to pastebin or

1) That was my initial suspicion, but when I run ps -aux | grep "java", but there it doesn't show any other program running. I kill the process and start again and it locks.
2) When we fire backup on Slave, the whole core hangs after a while and also replication stops. This was not happening with our earlier setup of solr3.6

Re: Solr 4.3 Master/Slave Issues
Posted by Shalin Shekhar Mangar <sh...@gmail.com>.
This can mean multiple things:
1. You had killed a solr process earlier which left the lock file in place
2. You have more than one Solr core pointing to the same data directory
3. A solr process is already running and you are trying to start
another one with the same config.
