Issue Problems with sw-engine

[straddi]

I've noticed that the cache in my RAM keeps getting larger and larger at the same time, and the system crashes. The server is no longer accessible from outside. A restart fixes the problem, but it keeps happening again at the same time.

I noticed that the sw-engine causes an enormous server load during this time.
Therefore, I deactivated it and Plesk with service sw-engine stop && service sw-cp-server stop. A query with service sw-engine status shows that it is deactivated. However, it is still apparently active, as shown in the attached image.

This is exactly the time at which the cache starts growing when sw-engine is enabled.

Could be a number of things. You can try reinstalling the package, in case it's corrupted. Let's check the logs, shall we?

1. Share /var/log/sw-cp-server/error_log and /var/log/sw-cp-server/sw-engine.log
2. Install atop and change the interval to 20 secs. Then share a screenshot of the atop logs during the issue.

I installed and started Atop



and configured as follows

# /etc/default/atop
# see man atoprc for more possibilities to configure atop execution

LOGOPTS=""
LOGINTERVAL=20
LOGGENERATIONS=28
LOGPATH=/var/log/atop

However, only one log file is stored in the path, namely the one from the start of the atop application (atop_20250417)

Yes, that's fine. When the issue happens again, open that file with atop as shown in the guide I linked, and go to the timestamp when the problem happened.
