python3 /usr/sw/loads/soltr_9.9.0.34/scripts/vmr-solaudit -d --daemonize

does anyone else see a curious 5 minute cpu spike on the PubSub+

02:45:52 PM 1000001 18428 7.00 3.00 0.00 10.00 0 python3

Strace shows this at the time for the pid.

Any Answer is helpful.

Interesting, I'm kind of curious about your setup - can you pleases have more details?

• Is this happening when you are running a client using the Python API?
• Does this happen only when you have a local docker broker running?
• What activity are you doing when this happens/

This is happening when just the broker is running.

There is next to nothing being written to the log short of semp commands.

It appears to be caused by "Garbage Collection" on the PubSub+

When looking at this it doesn't to be the most optimal or efficient process.
