A bit later at ~2:16 the MasterLog [2] started to log sched daemons to

Hi Thomas,

For any/all HTCondor daemons, exit code 44 means that the HTCondor daemon in question failed to write to write or rotate a log file. I.e., the write() system call failed. Look at the filesystems holding the paths for LOG, LOCK, and/or EVENT_LOG via
  condor_config_val LOG LOCK EVENT_LOG

The most likely cause for this is the filesystem(s) in question were full, or fell offline (i.e. NFS mount failed if they are not local). BTW, I would encourage your to have these directories on local disk if they are not already.

Hope the above helps
