How to find out the reason for error 17883?

Hello, ereryone

I use MSDE in my system, and sometimes the following error occurs in MSDE. After that, I can not even access MSDE with the osql command.

Can anyone give some advice as how to deal with this kind of error or how to find the real reason? I have checked MS homepage, but I can not get the details of it.

Error: 17883, Severity: 1, State: 0 The Scheduler 0 appears to be hung. SPID 0, ECID 0, UMS Context 0x003B70F8

Thanks in advance.
