Got that error too (or a similar)

Found out that this error occurs when the comp is completly out of 
resources.
(load of 4 and 70% waiting I/O)

so the timeouts trigger.
In my case this happened to my old IDE-harddisks combined with a 
db-slave running on the same comp.
Also if you got a db (slave) ran on this comp you are connecting to you 
can get a similar error that mogile got no key.
