Opened: Aug 30, 2018 Severity: 2-Critical
-- High TMM memory utilization; -- Aggressive sweeper activated; -- the 'packet', 'xdata' and 'xhead' caches in the memory_usage_stat tmstat table have high 'allocated' and 'curr_allocs' numbers with a steadily increasing profile.
Degraded performance, possible TMM crash due to out-of-memory condition.
A fastL4 and a L7 profile (e.g. HTTP) are assigned to a virtual server.
Do not add a L7 profile to a fastL4 virtual server.
No memory leak in the TMM. Note: there are limits to what L7 profiles such as HTTP can do when attached to fastL4 virtual servers, and this fix does not change them. For more information see: -- https://support.f5.com/csp/article/K16446 -- https://support.f5.com/csp/article/K16783
