Irrelevant.  This affects caching but doesn't have anything to do with  
your issue.

Yeah - looks like your IMAP server is broken.  This is in your logs:

C: 5 APPEND INBOX (\seen) "5-Dec-2012 17:30:14 +0530" CATENATE (URL  
/INBOX;UIDVALIDITY=1246769611/;UID=185840/;SECTION=HEADER TEXT {31+}
C: [LITERAL DATA - 31 bytes]
C:  URL /INBOX;UIDVALIDITY=1246769611/;UID=185840/;SECTION=1.MIME URL  
/INBOX;UIDVALIDITY=1246769611/;UID=185840/;SECTION=1 TEXT {31+}
C: [LITERAL DATA - 31 bytes]
C:  TEXT {135+}
C: [LITERAL DATA - 135 bytes]
C:  TEXT {33+}
C: [LITERAL DATA - 33 bytes]
C: )
S: 5 OK [APPENDUID 1246769611 185860] Completed

So a message was added to your INBOX.  However, the INBOX is later  
attempted to be selected:

C: 8 SELECT INBOX
ERROR: IMAP read/timeout error.
C: 9 LOGOUT
ERROR: Server closed the connection.

For some reason your IMAP server is crashing when the INBOX is  
selected.  Not much we can do when the server is flat out crashing  
without providing an error message.
