[HTCondor-users] Schedd crash by setting concurrency limits by schedd_cron

["KLI (Thomas Kiesel)" <Thomas.Kiesel@xxxxxxxxxxxxxxx>]

Hello!

I get the following error on my test pool and i don't know how to fix it. Sorry for my bad English i try to explain so good i / google translator can. ;D
I set up a pool and defines for the schedd a cron job list with two cron job names corresponding to two concurrency limits (free_low_limit and free_high_limit). As i know the schedd creates new ClassAds for the cron joblist names on start. Now i want to execute periodically two scripts to set new concurrency limit values at run time. Persistent and Runtime config is enabled. But if i start condor the schedd crashes with the following errors.
Without the _LIMIT shedd starts but not set the concurrency limits.

 

condor_config:

SCHEDD_CRON_JOBLIST = FREE_LOW_LIMIT FREE_HIGH_LIMIT

SCHEDD_CRON_FREE_LOW_LIMIT_EXECUTABLE = $(LIBEXEC)/low_limit

SCHEDD_CRON_FREE_LOW_LIMIT_PERIOD = 30s

SCHEDD_CRON_FREE_HIGH_LIMIT_EXECUTABLE = $(LIBEXEC)/high_limit

SCHEDD_CRON_FREE_HIGH_LIMIT_PERIOD = 30s
