[Condor-users] Occasional stalls in the negotiation cycle

[Rob Pieké <pieke@xxxxxxxxxx>]

Every few negotiation cycles, something happens that is causing a ~10min 
pause. It always seems to occur when "Getting all public" ads, as is 
shown below from the NegotiatorLog.

Hopefully related, 'condor_status' currently takes a LONG time (2min+, 
instead of only a few seconds) to return any information, and I'm seeing 
a lot of the following in the CollectorLog.

4/19 14:44:08 Buf::write(): condor_write() failed
4/19 14:44:08 SECMAN: Error sending response classad!

Any suggestions as to where I could/should focus my debugging efforts 
would be much appreciated! :)
