What OS are you running on your IOC?
What clients do you have running against the IOC?
Are the clients that were connected before - still connected?
Do you have any diagnostics on what is going on there?
This is a superficial symptom. More information is needed.

Subject: EPICS-Problem

Dear Mr. Hill and Ladies and Gentleman,

we have got a "big" problem concerning an EPICS System. This is the error message:

Calling epicsThreadSuspendSelf()

This happens, when we try to talk to the running EPICS-IOC and we didn't talk to it a time ago (some hours). If we restart it, it works fine. But if  we wait and then try to talk to it, this will happen.I'm not sure, if it appears only due to a special command or if it is a general mistake!

Thank you for your answer,

Christoph Langer
