Jeff,
I found the problem.
The LDM user on ldm.michiganwxsystem.net has this crontab(1) entry:
*/30 * * * * ~/nawips/cleanup.sh 1>/dev/null 2>/dev/null
The script "cleanup.sh" has this command:
for semid in `ipcs | grep ldm | cut -f2 -d" "`; do ipcrm -s $semid; done
This command deletes the semaphore used by the upstream LDM database feature in
version 6.11 to manage concurrent access to the database.
Regards,
Steve Emmerson
