Opened: Jul 03, 2018 Severity: 3-Major
TMM crashes when it is releasing the memory used by a session that is terminated. Either one of the following error messages might appear in the TMM log: -- notice panic: ../kern/umem.c:4166: Assertion "valid type" failed. -- notice panic: ../kern/page_alloc.c:705: Assertion "vmem_hashlist_remove not found" failed.
TMM restarts, causing service interruption if the BIG-IP system is not part of a high-availability setup.
The memory used by a session is corrupted during the lifetime of the session. This issue happens infrequently.
There is no workaround at this time.
TMM no longer crashes when removing an access session.
