Solr Hangs
Hi All,
I am using Solr 3.0 and have 4 cores build into it with the following
statistics,
Core1 : numDocs : 69402640 maxDoc : 69404745
Core2 : numDocs : 5669231 maxDoc : 5808496
Core3 : numDocs : 6654951 maxDoc : 6654954
Core4: numDocs : 138872 maxDoc : 185723
The number of updates are very high into 2 of the cores, solr is running in
tomcat with the following JAVA_OPTS values "-Xms2g -Xmx16g
-XX:MaxPermSize=3072m -D64" .
When Solr hangs and I try to restart it I am getting the following error,
which does indicate that it's a memory problem, but how can overcome the
problem of hanging.
Error occurred during initialization of VM
Could not reserve enough space for object heap

Rohit - for debugging hangs you will can trigger platfom specific dump and analyze it.

Thanks Simon, did get that part, it was happening because solr was not able
to reserve enough memory when it had hung once. The server has 24G of memory
and I am try to start solr with "-Xms2g -Xmx16g -XX:MaxPermSize=3072m -D64"
option. But, this is not my main concern, how do I find out why solr hangs
and is there a way to automatically kill and restart.

That error has nothing to do with Solr - it looks as though you are trying
to start the JVM with a heap size that is too big for the available physical
memory.

That error has nothing to do with Solr - it looks as though you are trying
to start the JVM with a heap size that is too big for the available physical
memory.
