Re: 20020305: suominet

Hi Anne, 

Would you be so kind as to comment out:

#exec   "pqbinstats"


from your ldmd.conf file and watch to see if the errors vanish from your
logs?

The :35 minute really has me thinking it has to do with statistics
reporting. My guess is sendmail protocol which I am investigating further.

Keep in mind, any changes in your ldmd.conf file will not take place until
you stop your ldm and restart.

So..

Make change (comment out pqbinstats)

ldmadmin stop

now make sure ALL LDM rpc and processes have stopped

ps -ef | grep ldm

and/or

ps -ef | grep rpc

when none are appearing as active  no rpc or ldm owned processes
(generally less than one minute)

ldmadmin start

That should do it, and I suspect you will see the errors go away.

However, we may want the stats, so we may need to make future changes,
this is kindof a debugging process.


Thank you,

-Jeff
