redis server give an empty response on EXISTS command

[GoogleCodeExporter]

Redis 2.2.7 on ubuntu 10.10 as VPS on XEN System

sometimes, redis server returns an empty response instead of :0\r\n
to an EXISTS command. 

Create some keys as Hash keys and Delete it. 
After a Delete if you check of key existance using EXISTS, the server returns 
an empty response. 

I'm assuming now that empty response is equivalent to :0\r\n but i'm not sure 
it's right. 

I'll attach an auto-produced log information

R: is a response
S: is a command
before S: or R: you have a time information
it seems to happen randomly

If the time format is HH:MM:DD, the connection will be timed out when EXISTS is 
called. It seems you're interacting with Redis on a pretty low level, where a 
read operation against a closed socket results in 0 bytes (which should be 
interpreted as EOF).

Thanks, that was a typo. I meant hh:mm:ss.
