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

Thanks,

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.
