> Getting an OutOfMemoryError after running for several days. Attached is a thread dump
showing hundreds of orphaned IoSender threads. At any given time there are fewer than 50 clients
but many of them are not "well behaved". Here is the stack trace for the error but I don't
really believe the LDAP calls are really the problem:
> 2015-05-08 03:01:19,000 ERROR [IoReceiver - /10.96.250.6:59923] (server.Main) - Uncaught
exception, continuing.
