Impact of reducing TMM memory allocation
I've currently got my tmm memory allocation set to the default value
sys db tmm.proxyssl.cachesize { default-value "2621440" scf-config "true" value "2621440" value-range "unsigned integer min:0 max:18446744073709551615"
I've recently had issues with my device where tmm memory hits 95% causing aggressisive disconnections in order to reduce memory usage. I'm looking to reduce the mem allocation, but not sure what is an acceptable value or how to determine a value acceptable for my device in relation to current operations.
Is there a way of determining an acceptable value? also what will be the impact if I just reduced the value to about 1.7G?

Are you certain your device is not facing a DoS attack perhaps? High memory utilization could indicate a DoS attack, and F5 reaping connections to mitigate it.

Doesn'nt look like a DoS attack, I think the default setting was the issue. After confirming with F5 support on the value proposed we reduced the capacity and we are working fine.
Thanks
