Hello,
I am developing sequencing code using a case tool called
Rhapsody. This is part of the Keck Interferometer control
system and talks to EPICS PVs via a Keck Keyword API layer on
top of Channel Access. I assume the Keyword API is built
on the portable CA libraries. Currently running EPICS
3.13.0 Beta 12 at Keck and I assume the Keyword library
is linked to this. Well up until now my Keywords (PVs) where used
in two threads and seemed to work just fine. But I had
to add a keyword to a third thread and the following error
message is given:
CAC: unexpected select fail: 9=Bad file number
Segmentation fault
And my program segment faulted as shown. Found this
message in $EPICS/base/src/ca/bsd_depen.c. It is not
that the code does not run but rather this happens after
the code is running for a few minutes. Any ideas about
exactly what is going on here? Could an upgrade of EPICS
help this situation?
Thanks,
Len
