Re: Solr stops responding

[Fuad Efendi]

Try to use Tomcat... I never had SOLR-deadlocks (I believe) on 4-CPU  
SLES 10 server; only OutOfMemoryExceptions (possibly due to faceting,  
and significant memory fragmentation)

Recent OOM happened because I run MySQL on same server, and I overloaded it...
OpenBitSet & Faceting is main memory constraint for SOLR. OOM may  
happen even with huge but fragmented free memory available. GC can't  
optimize blocks locked by 'synchronized' statements (possibly...)
