Using certain iRules on virtual servers with OCSP Stapling enabled on the Client SSL profile might cause OCSP requests to be reissued, resulting in a memory leak. You may notice warning messages similar to the following in /var/log/ltm: warning tmm: 011e0003:4: Aggressive mode sweeper: /Common/default-eviction-policy (0) (global memory) 115 Connections killed.
TMM memory used increases gradually, eventually the aggressive mode sweeper is activated.
This occurs when the following conditions are met: -- Virtual server with OCSP Stabling enabled. -- iRule attached to the virtual server that uses SSL::renegotiate.
Using certain iRules on virtual servers with OCSP Stapling enabled on the Client SSL profile no longer causes OCSP requests to be reissued, so there is no associated memory leak.
