Re: [Condor-users] Network problems

Hi Adam,

My guess it that your shadow's have used all the (100) available  
ports - see section 3.10.8.2 of the manual. The maximum number of  
running jobs you can support is 19 and I suspect you are limited to  
100 ports by firewall restrictions. Your two options are to define  
MAX_JOBS_RUNNING or enlarge the firewall hole and increase the number  
of ports by changing HIGHPORT and LOWPORT.

Cheers,

Andrew
