Hi Thomas,

Indeed, there is a clear bug where if ALLOW_WRITE_COLLECTOR is not set in the config, condor_check_config will trip on an undefined variable. I've made a ticket and supplied a fix https://opensciencegrid.atlassian.net/browse/HTCONDOR-1186, but it might be a couple releases out until it gets included since we just hit a code freeze last week.

A quick fix is to add a line defining "allow_write" as an empty string at line 59 in condor_check_config:

diff --git a/src/condor_scripts/condor_check_config b/src/condor_scripts/condor_check_config
index b3bdf2a1df..7fe526d49f 100755
--- a/src/condor_scripts/condor_check_config
+++ b/src/condor_scripts/condor_check_config
@@ -56,6 +56,7 @@ def check_dead_allow_write():
     Look for extraneous ALLOW_WRITE_<daemon>
+    allow_write = ''
     if 'ALLOW_WRITE_COLLECTOR' in htcondor.param : allow_write = 'ALLOW_WRITE_COLLECTOR '
     if 'ALLOW_WRITE_STARTD' in htcondor.param : allow_write += 'ALLOW_WRITE_STARTD '

Hi all,


Hopefully a quick fix but I’m testing out Condor 9.0.13 in our test environment and went to test out the new condor_check_config command but unfortunately got a rather interesting Python error on our schedd machine. Has anyone seen this kind of error before?



Traceback (most recent call last):
