Hi All -
Lately we have several CA crashes which may be buffer problems on
our IOC's. We're using EPICS R3.13.4 on MVME-167 and MVME-2700
targets.
When I run 'netStackSysPoolShow' I see 2048 mbufs. This looks
good to me. Are there other useful checks from the shell I can
run to assert my image is built in the best manner possible?
The INVALID FILE DESCRIPTOR message below seems strange to me.
Has anyone seen that before?
Thanks for any help,
-Matt Rippa
