Hi Hinko,


Since it generated a core file you should be able to do some more debugging with gdb.  For example what are the values of "size" and pMsg->postsize in caserverio.c?  You might be able to figure out what PV this is.


Mark

Dear EPICS users,

here is the error I got from the IOC running EPICS base 3.15.4:
