- cronjob runs a bash script under trusty, with jsub -l release=trusty ~/exec.sh
- bash script exports the Ruby bins to PATH, sets the local ruby, then runs the ruby script, via:
export PATH="$HOME/.rbenv/bin:$PATH" export PATH=$PATH:/data/project/musikbot/.rbenv/versions/2.1.0-dev/bin rbenv local 2.1.0-dev cd ~/MusikBot ruby -d core.rb
Sometimes this is successful, sometimes it is not. The cron runs every 10 minutes but the Ruby script only successfully is ran about every 60 to 90 minutes. There is seemingly no rhyme or reason to the timing, but it is persistent. This has been going on for about two days.
There are two error logs, dash.err for the cron and exec.err for the bash script. Both have similar output:

Exception `LoadError' at ruby - Permission denied -- core.rb ruby: Permission denied -- core.rb (LoadError)
This output is from the -d flag used when running the Ruby script. Without the debugging output you see only ruby: Permission denied -- core.rb (LoadError). It is unclear if this is actually a permissions issue as I've made everything in the entire directory read/write/exec with chmod 0777.
This issue happened to me about two weeks ago, and somehow resolved itself. However, that time I was getting the error about permission denied when attempting to write to perm_clerk.log which is the log file for the Ruby script. That file also had full rwx permissions. I'm not sure if that issue is related to this one, but thought I'd mention it.
Any help is greatly appreciated!
