Hey everyone, we're running into some operational problems with our SOLR production setup here and were wondering if anyone else is affected or has even solved these problems before. We're running a vanilla SOLR 3.4.0 in several Tomcat 6 instances, so nothing out of the ordinary, but after a day or so of operation we see increased response times from SOLR, up to 3 times increases on average. During this time we see increased CPU load due to heavy garbage collection in the JVM, which bogs down the the whole system, so throughput decreases, naturally. When restarting the slaves, everything goes back to normal, but that's more like a brute force solution.
The thing is, we don't know what's causing this and we don't have that much experience with Java stacks since we're for most parts a Rails company. Are Tomcat 6 or SOLR known to leak memory? Is anyone else seeing this, or can you think of a reason for this? Most of our queries to SOLR involve the DismaxHandler and the spatial search query components. We don't use any custom request handlers so far.
