Re: [HTCondor-users] condor_master.exe High CPU Usage

Hi TJ,

Unfortunately this happens sporadically. As you can see this message is printed repeatedly in the MasterLog file (I have found over 10Klines in 1 second of time).
When the user comes to us with the problem, the point in the MasterLog when the problem started has already gone.

This user found that behavior only once a year ago but without evidence that it was the same problem.

Do you have any suggestion how we could proceed? What does this indicate, communication failure, network failure, etc? What are the point in the code that this could be happening?

this is a symptom of a bug in the code,  if you can find the point in the log file where is began, then
there might be a clue in the log how the master got into that state.

Also, once the master gets in this state there is no way to fix things.   You'll just have to restart
all of the daemons, including the master.
