pilersearch.service: Supervising process 1355 which is not our child. We'll most likely not notice when it exits.

[MaxSmir]

I'm having a problem with the pid file. It says the argument is invalid.
and also pilersearch.service: Supervising process 1355 which is not our child. We'll most likely not notice when it exits.
The audit also doesn't report invalid login attempts. Is this normal?

Piler version 1.4.8
Manticore version 13.13.0
