Switch collectors fails to start after system reboot
After the Oct. 15 power outage, the following files needed to be removed on nimisrva
in order for the switch_collector.sh to run:
The switch_collector.sh script detects the presence of the /tmp/switches.db file,
but does not check if a switch_table_db_parser.py process is running.
This failure occurs when nimisrva comes up and the /tmp/switches.db file exists.
