nk thread kernel parameter

[TC123]

Hi.

I wanted to know, that if an issue is coming, where ,on running a load test, the memory of the APP server(unix) increases, but does not come down once the test is over, in that case, does tuning the nk thread paramter help in teleasing of the memory..???
plz answer soon

Well,

Tuning a kernel parameter is dependent on a lot of things. Actually, the nkthread parameter specifies the maximum number of threads that all processes combined can run at any given time. This is system wide approach. Actually, do we have the default parameter now in setup? It should be (nproc*2)+ 15 or 16 by default I guess.

Also, what is the exact issue you are facing now? Were there any updates done before you experience this issue? What is the OS relase and memory you have in setup?

We also need to make sure that this issue is not because of anything else before you modify the parameter. I'm not sure if the modification of this parameter would help here, however, more information in this regard would help anyone who's gonna address this issue in this forum!

Yep...DB is correct, we do not make changes in the kernel parameters untill we are sure.
Moreover, your issue is somewhat related to memory. Try searching in "top", which process is utilizing most memory, is this the same application that is stopped.
Try "ps -ef | grep -i <app>" to ensure if the process is still running..
