Hey, there happened to be multiple DOS causing sa-learns spawned tonight. The swap was thrashing, things were at a standstill except for basic shell operations. I suggest we avoid this by modifying the script called by cron to check if a pid exists for sa-learn, and to die if it does. I haven't tested this, but it might look something like: #!/bin/bash pid=`pidof -s sa-learn` if [ $pid ]; then echo "sa-learn already spawned" else echo "sa-learn can be spawned" fi
Any other input to prevent this from occuring again? Something like this should definitely be on the new servers. Cheers! Ryan _______________________________________________ HCoop-SysAdmin mailing list [email protected] http://hcoop.net/cgi-bin/mailman/listinfo/hcoop-sysadmin
