> 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.
