Symptoms

Very regularly receiving OutOfMemory exceptions when performing searches via the SES 11.1.2.2 search interface. There is no pattern as such but on few occasions searching with bigger phrases have resulted in this OOM exceptions. In the AdminServer log following are seen -
  
#### <> <> <>
java.lang.OutOfMemoryError: Java heap space.
java.lang.OutOfMemoryError: Java heap space

Once this error occurs nothing works and have to restart the entire SES midtier to continue operations. Every day , 4 to 5 times SES has to be restarted. Crawling/Indexing of sources never produce this error. It's only the searches that are causing this OOM errors.
