Re: [HTCondor-users] OsUser job-router crashes

Hi Dan,

This issue seems different (but possibly related) to the previous threads issue. Looking at the code, this error should print out a ClassAd (key = value pairs) before the provided debug lines. Could you share those lines. Feel free to clean them up as needed (remove usernames, hostnames, etc) or send it directly to me.

Subject: [HTCondor-users] OsUser job-router crashes

 

Hi,

I know there have been some other threads about this, but we are still seeing regular and frequent job-router crashes with the following:

03/22/26 03:14:12 Failed to find OsUser or User in job ad.
03/22/26 03:14:12 ERROR "Failed to initialize user ids." at line 64 in file /var/lib/condor/execute/slot1/dir_3041422/scratch/userdir/build-b0FsGA/BUILD/condor-25.0.8/src/condor_utils/set_user_priv_from_ad.cpp

Looking back through the list, I note that at least one other user appears to have experienced a similar issue but that it was apparently resolved when they updated to version 25. Our entire estate (worker nodes and CE’s) is now running 25 but we haven’t seen any reduction in these errors. 

Any assistance would be greatly appreciated.

Thanks,
