[CLOSED] IMAP connection broken - WHY IS THIS HAPPENING???? HELP!!!!

[paritycheck]

My email program now and then stops all of a sudden showing a blank page especially when I try to access the inbox when a large attachment has been delivered and I get this error:

 

PHP Notice:  Unknown: [CLOSED] IMAP connection broken (server response) (errflg=1) in Unknown on line 0

 

Whats going on and how can I set up an error handler to take care of this - when I refresh it a couple of times it finally works...help please ???
