[Condor-users] USER_JOB_WRAPPER issue

I;m trying to limit job resources somewhat by introducing a job wrapper, and am having the following issue.

The testing submit file is

   universe = vanilla
   executable = /bin/uname
   arguments = -a
   output = uname-$(process).out
   error =uname-$(process).err
   log = /tmp/uname.log

   queue 100

and the wrapper script is simply (for testing)

   exec "$@"

with USER_JOB_WRAPPER=(path to wrapper script). The script has 755 permissions on all nodes.

When this is run, I see all the test jobs put into a hold state, with the following hold info:

HoldReason = "Error from starter on vm2@xxxxxxxxxxxxxxxxx: Failed to execute '/etc/condor/condor_job_wrapper.sh' with arguments -a: Exec format error"
HoldReasonCode = 6
HoldReasonSubCode = 8

Can anyone provide insight into this "Exec format error" issue?
