I emailed IT about this issue (multiple times), that maybe they should prevent users from overfloading the system, instead of waiting for it to happen and then clean up the mess (and leave me out of a job for 6 hours). However, they feel we should explain the usage of the cluster properly to new users, so that it wouldn't happen anyway.

So maybe some words of advice are necessary ;-)

Well, Kenny give MySQL lessons to him ... He should have mentioned that 
a sql server can only handle so many connections at the same time :p
So who is to blame... The teacher or the student ;)

Let's add this one to the list as well

Btw did each job also connect to psbsql02 bringing that server (and 
hosted websites eg. Bogas) down as well ? (Kenny was complaining about 
this yesterday)

Tom,

You submitted 82500 jobs, which is normally beyond the limit of 
70.000. Can you empty your queue please? If not, we will delete them 
for you.
thanks

Well, yesterday i did submit a lot of jobs, but i was unable to empty my
queue ..

  
      
        
Did someone submit lot's of jobs to the cluster? Restarting the cluster
master on chione  results in a segmentation fault. If you did, please
empty you queue so that we can restart the master. Please notify us.
