Re: [Condor-users] Parallel Jobs + Chirp in 7.6.4

[Mark Calleja <mc321@xxxxxxxxx>]

Hi,

We're seeing the same problem since upgrading 7.4.4 -> 7.6.4, which is a 
real pain. I note that another user reported the error for 7.6.2 back in 
August 
(https://lists.cs.wisc.edu/archive/condor-users/2011-August/msg00033.shtml), 
but unfortunately his post didn't get a reply. We're loathe to downgrade 
back to 7.4.4, so any help from the community and/or developers on the 
issue would be greatly appreciated.

Best,
Mark
