DOS Layer 7 memory consumption
Hello, Recently we had a problem where BIGIP started killing several tcp connections. Analyzing the issue we discovered that the TMM "used memory" was over 85% and BIGIP began to kill the connections. So, we started looking why TMM was using so much memory and found out that the "Memory Pool" with the name "DoS Layer 7 ACY" was using 2.7G (a much higher value than any other entry in the memory pool table). Does this "DoS Layer 7 ACY" use TMM's allocated memory? If yes, is there a way to reduce this amount of memory? ps: BIGIP VE 12.1.1 (LTM, ASM, AVR, AFM and AAM); We use "DOS Layer 7" feature in 15 Virtual Servers (mainly to block bots); We have 5.6G allocated to TMM. Thank you, Cristiano
