Re: cac_select_io Segmentation fault

[Ralph Lange <Ralph.Lange@bessy.de>]

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
