-------------------------------------
Summary: java.lang.OutOfMemoryError: unable to create new native
thread
Key: QPID-6535
URL: https://issues.apache.org/jira/browse/QPID-6535
Project: Qpid
Issue Type: Bug
Components: Java Broker
Affects Versions: 0.32
Reporter: Mark Soderquist
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.
