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


vtpc2.starp.bnl.gov Thu Apr 28 13:32:23 2005 ../iocinf.c: bad UDP msg from port=1030 addr=82c73cbe

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,
