[Samba] HELP: Samba server crashing on me

[Jobst Schmalenbach]

This is ONLY a guess:

 * signal 11 means invalid memory reference, so I would check your RAM
   and even your harddisks, it could be a page fault.
   (find some other ram, put them in and run it for a while).

 * may, just maybe your problems from earlier "Unable to connect to CUPS server"
   have had too many pointer allocations/references that the next one in the 
   chain crashed the server, fix this and check again.


this is what I would do first.
