Severity: 3-Major


Repeated TMM service crash SIGBUS with memory copy operation at the top of stack trace.


TMM crash. The program terminated with signal SIGBUS, Bus error.


TMM loads filestore file and size of this file is smaller than the size reported by mcp or if this ifile store is not present at all. This condition is possible due to - filesystem errors/corruption or - BIG-IP user intervention. Filesystem error might be due to power loss, full disk or other reasons.


Manual copy of the "good" ifile store and forceload on the previously bad unit. Usually trivial, but error prone. Another workaround is clean install, if possible/acceptable
