Hardware compression might cause excessive memory consumption and eventual tmm crash as it exhausts available memory.
tmm crashes, drops core, high memory consumption indicated. Traffic disrupted while tmm restarts.
This occurs on the BIG-IP 2000s/2200s (C112) and 4000s/4200v (C113) platforms using hardware compression being used with greatly varying payload (xbuf) lengths directed at compression.
Do not use hardware compression.
Interface to hardware compression has improved allocation strategy.
