Re: [Condor-users] condor_view server running wild

["Robert E. Parrott" <parrott@xxxxxxxxxxxxxxxx>]

Being persistent, I'll ask the question again:

Does anyone have the condor_view server running without it taking up 
100% CPU time, and does anyone have a suggestion as to the cause of the 
problem I'm seeing with the condor_view server?

Thanx again,
rob
