Under they high load when there are many Threads the cache > can grow significantly. Plus if a Thread is terminated its prepared > statements are not get cleaned introducing a memory leak. > A special background Thread should be introduced that will iterate over > {{stmCache}} performing the following: > - cleaning records for terminated Threads; > - cleaning records of the Threads that were not used for a long time. A > special configuration parameter can be set. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
