Subject: gateway error message

 

We installed a new linux R3.14.6 gateway yesterday and in less than 24 hours
the log file filled up with ~48k lines of error messages, all referring
to the same pv. The error message is:

Oct 26 08:11:22 !!! Errlog message received (message is above)
----------dump This=0xa0a9c28---------
 dimension=0 app-type=16 Scalar
 prim-type=aitString(aitEnumString)
this=0xa0a9c28 string=0x4041eac8<User Request PS OFF>, length=19, buf length=20, type=Allocated
 ref-count=1
 total-bytes=64, data-size=28, element-count=1
 LocalDataFormat
--------------------------------------
filename="../../../../src/cas/generic/casStrmClient.cc" line number=607
server tool changed bounds on request - get notify with PV=TMMSTATUS type=16 count=1

The addresses following "dump This", and "string=" change with each message.

The pv in question, TMMSTATUS, is a string out record, written to very seldom
by a sequencer code. We don't know anything at this time about clients using this record.

Would a misbehaving client(s) cause this behavior? Is it really an error? Is the client
getting its data in spite of the message?  If data is being delivered, it might be much
harder to find the "bad" client?

Or am I way off track?

Has anyone else seen this?

Thanks for your help.
Joan
