Severity: 3-Major
Intermittent TMM crash when using PEM. The crash backtrace indicates the TMM was caught in an infinite loop servicing timer completion events.
Traffic disrupted while tmm restarts.
Crash can (rarely) be triggered by a client disconnecting and immediately reconnecting a TCP connection to a PEM virtual.
This issue has no workaround.
A bug in timer cleanup handling during TCP disconnect processing by the PEM module was fixed.
