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
F5 i5800 vCMP dedicated high memory
Hello Guys, a client have 2 F5 i5800 physical appliances and there is requirement to use virtualization and have more than one F5 context/vCMP. So I already configured and installed 2 vCMPs which are HA pairs and work fine. Active/Standby vCMPs reside on different physical F5s. BUT after a few weeks I saw F5 hardware appliances are working constantly at more than 90% memory usage. Everything is working fine but this is bothering me. Could there be any issue or maybe this is normal? I was searching for more than 2 weeks here and other resources without any result. I also used iHealth but there was no "memory usage warning" or something similar. Can anyone give some advice on this?High Memory utilization observed in Solarwind SNMP Manager.
Hey Folks! Could you please help me here? I have total 4 F5 LTM 1600 appliance. 3 of them are running on 11.2.1 HF6 and one is running on 10.2.3. I have integrated an external SNMP server i.e. Solarwind with all of these LTMs and I am seeing 96% Memory utilization for all of the appliances. It doesn't make sense to me, as there are 4 appliances and how it is possible to have 96% for all of them?  What could be the possible issue? Thanks mates! Regards, Darshan
