When tmm cannot expand the eXtremeDB database, it logs an error in /var/log/tmm: err tmm1[21087]: 01010004:3: Memory allocation failed: can't allocate memory to extend db size
Tmm does not crash but the eXtremeDB state is inconsistent with other tmms and could lead to unpredictable behavior such as virtual servers not working, iRules failing to work, bot defense failing to work
-- BIG-IP in operation -- A configuration change is made that causes tmm to allocate more memory to eXtremeDB. Examples include: - Adding a clientssl or serverssl profile - Modifying a datagroup - A bot defense sync occurs
