Re: [Condor-users] Condor_q hanging with SOAP

[Matthew Farrellee <matt@xxxxxxxxxxx>]

Where is the command handing in this log? I would expect to see a 
message about the command being deferred during the HTTP requests, and 
then it being serviced after.

The points where you say the command seems to hang are times when data 
transfer might be occurring, thus partially blocking the Schedd.
