Hi Florian,
could you be so kind to add the systemd service file you are using for this application? It would be useful. You can find it under /etc/systemd/sytem or /etc/procServ.d
Thanks in advance!

Hi Ralph,
I actually feared, that is has nothing to do with procserv or the ioc itself. Unfortunately I'm not an expert for systemd myself, but I hope someone in this forum has some ideas....
Cheers, Florian

Hi Florian,
Doesn't the third line of your log
Hey all, I currently have a problem with procserv. I'm using the latest commit from github compilied on Raspbian OS bullseye. I used manage-procs to create a service but the service gets stopped every now and then. The actual runtime seems to be quite arbitrary. Sometimes a few secs sometimes several hours. The log output does not really contain any helpfull information. Any idea what could causing procserv to shut down? CPU and RAM usage are way below 10% when the IOC is running. Cheers, Florian pi@scatterchamber:~ $ systemctl --user status procserv-epicsioc.service ● procserv-epicsioc.service - procServ for epicsioc Loaded: loaded (/home/pi/.config/procServ.d/procserv-epicsioc.service; enabled; vendor preset: enabled) Active: inactive (dead) May 23 10:10:17 scatterchamber procserv-epicsioc[58686]: 2022/05/23 10:10:17.505 drvModbusAsyn::doModbusIO port chillerReadReg error calling writeRead, error=PilotONE-187144:502 TCP timeout> May 23 10:10:18 scatterchamber procserv-epicsioc[58686]: 2022/05/23 10:10:18.604 drvModbusAsyn::doModbusIO port chillerReadReg writeRead status back to normal having had 1 errors, nwrite=6/>
i.e., the next one

suggest that systemd is deliberately shutting down the IOC?
The following log lines definitely look like procServ was told to shut down the child process.
I'm not a systemd expert enough to know what could cause that (wrong dependencies between services maybe?), but this doesn't really look like something originating within procServ or the child process.
Cheers, ~Ralph
