[BlueOnyx:24381] Fail2Ban eating resources

[Colin Jack]

Good morning all.

I have just replaced DFix2 with Fail2Ban on an old 5208R CT and it seems to be slowing everything down :-/

Cpu(s): 20.9%us,  4.6%sy,  0.0%ni, 74.4%id,  0.0%wa,  0.0%hi,  0.0%si,  0.0%st

  PID USER      PR  NI  VIRT  RES  SHR S %CPU %MEM    TIME+  COMMAND

 1200 root      20   0 1283m  10m 2588 S 120.3  0.1  11:50.83 fail2ban-server

The server is being hammered by spammers and dfix2 didn't seem to be doing the job but now it is very laggy with fail2ban installed.
Also got APF installed obviously.

Any thoughts?

Thanks

Colin
