Hello,
I started the upgrade of CSCP 3.7 -> 3.7.4 via GUI and it got stuck. So I did some research on internet, and found a way to start it manually via lcmagent-apply.tcl here:

That was probably not a good idea because now the upgrade is in loop. It runs for aprox. 2 hours, succeeds and restarts the server, only to find out it is somehow still running 3.7 and starting the upgrade again. I am attaching the latest Install and Apply logs.
