Do you have an exact sequence of operations to reproduce this, or can explain 
the circumstances (e.g. timeout between issuing these commands)?

Thanks,
Pieter

That's the cli copy-paste. I was trying to delete certain keys. I had deleted 
one and wanted to list out rest out the pattern . When the error happened 
(There was no timeout - may be 4-5 seconds delay from me between each command), 
I tried keys command without arguments - and looked like command came back 
working immediately after the error. Well, I couldn't reproduce this though. 

BTW, these are two 64bit machines and are equipped with public IPs.

Thanks for the info. Because this can't be reproduced and the details you give 
don't clearly point towards a possible cause, I'm closing this issue.
