Hello Abdalla,

 

Recently, I’ve got the similar problem, that is simply processing :SysReset does not restart the IOC. However, the IOC log explained, which says: “waiting for caPutLogTask to terminate”. Finally, I got into the IOC console via telnet and restart it.

 

I’m not sure if you had similar pending tasks that prevent the rebooting, but that’s all I have learned, hope it helps.

 

Thanks,

Tong

Hello Andrew

 

Although the issue does not appear on an IOC on the same server, I found out that the IOC is using relatively older modules versions; asyn 4.38 and stream device 2.8.10. I will try updating them and re-build the IOC.

 

Best Regards,

Abdalla.

Also what version of EPICS Base is this IOC running, and do you see the same problem from other IOCs running the same Base vesion?

Hi Abdalla, is the hanging issue repeatable for your StreamDevice-based IOC? What happens if you simply type “exit” at the EPICS shell? – Yong

Hi

 

We have a device controlled via Stream device and the IOC also has devIocStats module configured. When rebooting the IOC by writing 1 to “:SysReset.PROC”, the IOC does not exit, the IOC shell prints the message “IOC Reboot Started” I think and nothing happens, while on most other IOCs it is working well. What could be the issue here?

 

Best Regards,
