I was just wondering could this be a python version issue?

ls /usr/bin | grep python*
abrt-action-analyze-python*
python*
python2@
python2.6*
python2.6-config*
python-config@

I assume I am using python 2.6?

EDIT This also used to never happen. The other thing I noticed was the process won’t die and will remain seen when you do ps -ef
