Symptoms

In some, very rare circumstances SSL can incorrectly re-use an object which in even more rare circumstances can cause an infinite loop in TMM resulting in a crash. /var/log/ltm contains this message: "01010004:3: Memory allocation failed: Temporary keys"

Impact

Traffic disrupted while tmm restarts.

Conditions

SSL attempts to load the ephemeral keys and fails to do so.

Workaround

None.

Fix Information

The failure case has been removed, so TMM will no longer crash due because SSL attempts to load the ephemeral keys and fails to do so.
