I have a strange problem. The FNAL site is being thrashed by hundreds of copies of /tmp/grid_manager_monitor_agent that run on the gateway, spawned by the fork queue. Each instance takes 14M of memory and before long all the system memory is used. They are all from the same user, who submitted a lot of jobs a few days ago, but killed them with edg-job-cancel. What is particularly strange is that I killed 700 of them this afternoon. After 6 hours there were more than 200 running again. At the moment I have to monitor manually. Any thoughts of the cause or the solution would be appreciated. THanks, Ian
