Hi Recently I edited my configurations to use mongo for NodeStoreService and FileDataStore as customBlobStore. The problem I am facing after this change is that my server has become cripplingly slow. I am on CentOS 6.5 64-bit. On viewing the htop on my server, I find that the java process threads are maxing out all the CPU cores on my server. I took a thread dump (attached) of the parent java process to analyse the threads hogging the CPU as advised in [1].
As per what I see there is a "GC task thread (ParallelGC)"" running on each of the CPU core and is consuming the maximum CPU. I am attaching the thread dump for reference. I would like to understand, why is this happening and how can this be resolved. Since I totally stuck on this, a quick response from you experts is highly appreciated.
