If connection mirroring is enabled on a BIG-IP HA configuration with connection pooling (OneConnect) also enabled, TMM on a standby member may core with a SIGFPE, after logging a message containing the following string in the TMM log: 'panic: TCP4: HUDEVT_EXPIRED (Connection expired) bad pcb magic (0x00585858)'.
TMM logs errors, generates SIGFPE messages and cores until connection mirroring is turned off.
This may occur when enabling connection mirroring on a BIG-IP HA configuration with connection pooling (OneConnect) also enabled.
You can use one of the following to work around the issue: -- Turn off connection mirroring. -- Turn off connection pooling (OneConnect).
Resolved TMM error message 'HUDEVT_EXPIRED (Connection expired) bad pcb magic (0x00585858)' and TMM core on standby member of HA configuration with connection mirroring and connection pooling (OneConnect) enabled.
