Error trying to run sql jobs

I'm using sql server 2000 sp4 and I get the attached error msg when I try to run a job . No changes have been made to the server to trigger this error and there's plenty of memory & storage available. I've seen this before and I know a reboot will fix the problem, however I'm unable to continue to do this on a regular basis.

Does any know how to resolve this issue without rebooting ?

I'm nearly out of points, hence I've only allocated 45 but this will be changed to 250 when i get more

How much memory is SQL actually being allocated? Have a look at the Memory section of Task Manager.

What else is running on this box? IIS?

2Gb has been allocated and its using 1.26Gb.

It's running citrix & IIS services, unfortunately these can't be stopped.
You may find you're having RAM Issues.

IIS and SQL are notorious RAM hoggers and are not reccomended to be running on the same box.
