Under certain circumstances, while processing a configuration update to an ltm policy which contains a doncition with a numeric arguments (e.g. 'index'), the tmm could write a byte just beyond the boundary of an allocated buffer. This could cause tmm to crash while perfoming a subsequent memory allocation.
When this condition is hit tmm continuously crashes as it reads its configuration. Traffic disrupted while tmm restarts.
This crash rarely happens, but when it does, it does so consistently. The problem is related to numeric parameters added to conditions.
If possible remove the numeric parameters to the action.
The condition which could cause memory corruption in tmm on loading a policy which contains conditions with numeric parameters has been fixed.
