[Condor-users] Condor 7.7.5: MasterLog is flooded with ProcAPI errors...

[Rob <spamrefuse@xxxxxxxxx>]

Hi,

After starting the Master daemon, the MasterLog looks like this:

and zillions more of the last lines continue to flood the MasterLog at a rate of 5 lines per second.

The program with PID 999 has nothing to do with Condor. The file /proc/999/stat contains

999 (ddclient - slee) S 1 988 988 0 -1 4202560 29441 202449 0 0 69 54 90 208 20 0 1 0 5837 10022912 1249 4294967295 134512640 134516240 3217069360 3217068344 8217622 0 0 128 16385 3225853652 0 0 17 0 0 0 0 0 0 134520336 134520752 152264704

If relevant:
this is currently happening on two computers with kernels 3.3.4-1.fc16 and 3.3.6-3.fc16; the first is the central Condor master (with a large pool), the second is a Condor master (without a pool) that flocks to the first one.


Why is this happening?
Or is this an indication that something is going wrong elsewhere?
Any suggestions?


Rob.
