solrnet - Solr stops responding (or slows down to molasses)...(Solr newbie) -

-

running multi-core solr under tomcat 6.0 /win 2008 server , asp.net queries via solrnet. 1 of cores huge i.e. ~25 million documents (~20 gb disk-space) , several fields. other 3 cores smaller (few gigs each).

after couple of queries large index, solr slows down dramatically , stops responding i.e. can't open admin console. if restart tomcat, things again works ok few more queries , molasses stop. have checked machine ram , processor usage, both <50% utilization.

i not sure issue might - memory leak? how can go finding issue? don't know solr/tomcat logs , logs should looking at.

hope can help.

you'll have tune jvm memory allocation -xms , -xmx settings. see:
