Experimental Physics and Industrial Control System
Hello everybody,
I have a question regarding the reasons why a scan thread can be
suspended. I have a running IOC and at a certain moment the IOC breaks
with following message:
epicsStrDup: mallocMustSucceed(1) - malloc failed
Thread scan2 (0x9c2b038) suspending.
I have found in the tech-talk messages following reason which seems to
be the same problem that mine.
https://epics.anl.gov/tech-talk/2013/msg00154.php
The IOC is on a network where many devices are sending packages to the
CA network, but nobody is answering because other devices are switched
off (the traffic in the CA is very high).
Is it possible that the segmentation fault is caused by a network
congestion? Can the scan thread be suspended by a higher network traffic?
Thank you very much in advance for your answers.
