19.7 Legacy Series / Re: High CPU Usage since upgrade from 19.1.10 to 19.7

I've been running my firewall without local netflow capture enabled since yesterday and the CPU is normal.  So then I re-enabled it and let it run for a few hours to get the attached RRD graph.  Definitely using more CPU with local netflow enabled.

Still not as bad as before I reset the Netflow data, but definitely more than 19.1.

Literally just upgraded to 19.7 in the last hour and the first thing I noticed was CPU has gone through the roof to 99% at idle with minimal traffic.  Previously on 19.1 under the same load I would see next to zero CPU usage. 


last pid: 71370;  load averages:  1.40,  1.37,  1.42                                                                           up 0+00:36:46  12:21:45
49 processes:  2 running, 47 sleeping
CPU: 50.2% user,  0.0% nice,  0.2% system,  1.2% interrupt, 48.5% idle
Mem: 142M Active, 123M Inact, 296M Wired, 170M Buf, 1369M Free
Swap:

  PID USERNAME    THR PRI NICE   SIZE    RES STATE   C   TIME    WCPU COMMAND
35139 root          1 103    0 34996K 29804K CPU1    1  30:40  99.89% python3.7



I think I have alleviated the problem somewhat by resetting NetFlow data.  After I did that, CPU usage seems have dropped back to normal, with only the occasional spike from Python.
