Production system: allow CPU profiling

[ymartin59]

Hello
Every few months, spkrepo no longer answers to requests - nginx replies 502, and it looks like a service restart is required.
I am not sure if it is related but CPU is almost 60% all day long.

I would like to profile CPU usage in production but was unable to use any of "process attach" tool like pyflame or py-spy.

I am interested in a kernel update (current is 2.6.32) on that Ubuntu system version - to gain access to "perf" and probably have pyflame working too.
That kernel update is also probably a required to get docker running too.

When spkrepo runs properly in docker, we may plan a full system update/replacement - we will discuss later about it.

May you please plan such a kernel update on productive server?
Thank you in advance for your help
