I'm sorry, I'll be more specific. I'm running Ubuntu Server, 10.04. The problem has reoccurred with a little more information. It seems like a particular query fails, which causes the crash. I'm sorry to paste the entire printout, but I think it might help. I'm not sure what mailing list etiquette is for attaching files. 264490.001405 write: [destfd=6] [len=34] [VAR rack1ups ups.status "TRIM OL"] 264490.001440 mainloop: polling 3 filedescriptors
