Symptoms

tmm may restart while processing client request

Impact

Traffic will be disrupted while TMM restarts.

Conditions

- PingAccess profile is configured on the virtual server. - Client connection sends over 64k HTTP requests that result in BIG-IP's connection to the PingAccess policy server.

Workaround

Modify HTTP profile used by affected virtual to specify the limit of HTTP requests per connection "maximum requests per connection" to be less then 64k, e.g. 63000 or less.

Fix Information

Traffic will no longer be disrupted when client sends over 64k uncached requests on the same TCP connection.
