Experimental Physics and Industrial Control System
Hi,
I see that this subject in the archives but I am not having much luck
tracking this down.
A few days back we started seeing (from a window where the alh is
started):
CAC: post_msg(): Corrupt cmd in msg d00
../iocinf.c: bad UDP msg from port=47585 addr=7f000001
Of coures any window that opens an medm also shows the message:
CAC: Undecipherable UDP message from 127.0.0.1:47615
CAC: Undecipherable ( bad msg code 3328 ) UDP message from 127.0.0.1:47615
at Thu Apr 28 2005 13:10:25
(of course the 127.0.0.1:47615 47615 is dynamicly assigned.. so 47615
varies)
A telnet to some (not all) of the processors shows:
CAC: post_msg(): Corrupt cmd in msg d00
../iocinf.c: bad UDP msg from port=1030 addr=82c73cc1
iocLogtext shows

creighton5.starp.bnl.gov Thu Apr 28 13:32:23 2005 ../iocinf.c: bad UDP msg
from port=1030 addr=82c73ce5
one processor gives this on port=1029
several others on 1031
and one on both 1031 and 1032.

So I have rebooted the host, and also many of the processors. We are
running and I wont have a long access to these processors or the terminal
server for a few days. What if anything might I do to debugg???
Note this is old epics 3.12.. and I also dont have caSnooper etc..
These messages are only annoying right now, as they dont seem to have any
effect on our controls.
Right now only I loose sleep over this!
I greatly appreciate any advice or suggestions.
Thanks,
Bill Waggoner
