EPICS 3.13.10 is six years old and frozen. Lots of bugs have been fixed
since then.

(That's why I fear you might experience limited support enthusiasm.)
Any particular reason why you can't use a recent version?

(As you are connecting to Unix IOCs, you seem to have 3.14 built and
running.)
Cheers,
Ralph

I am trying to get a multi-threaded application working on SunOs 5.10
with connection to two UNIX IOC’s.
I get a seg fault for ellDelete, two statements from the end of
cac_select_io() (epics/r3.13.10/base/src/ca/bsd_depen.c).
The seg fault does not occur immediately but within a couple of
minutes (connections are to two IOC’s running on UNIX, with events
from two long records on each IOC, where one record on each system is
updated at 1 hz and the other at 10 hz).
Does the seg fault occur because r3.13.10 is NOT thread safe?
Does anyone have an example of a multi-threaded app using r3.13.10 on
UNIX?
Thanks,
Allan
