[Users] After many trouble-free years, one account times out on a message...

[Pierre Fortin]

Hi,

Network log below...  

Just to get this out of the way up front: I access my POP mail from
different MUAs and only CM is set to alter them on the servers.

This is really weird...  while running 3.9.3-101-ga9065a-dirty, all was
well, then today I noticed that messages which were appearing on my
Android K9Mail were not arriving via CM. Updated that instance to
3.9.3-173-g9b192e-dirty and the same thing happens...

Every time I hit Get, CM logs that it's deleting messages 1-17, then
stalls on message 155...  Looks like I need to read the RFC 

Checking my mail via the site's web interface, the number of messages
does not change, so no deletions actually take place.  This is confirmed
by the fact that every time I hit Get, it reports the same deletes of
messages 1-17 which are not really happening...

wireshark is useless due to encryption.

I have several accounts on luxsci.com and they are fine...  just one is
acting up...  

Using "telnet <server> 110", I can see all messages with LIST:
  [snip]
  154 9011
  155 13216
  156 6840
  [snip]
and can retrieve message 155 just fine...

Also, "openssl s_client -connect <server>:995" works fine too...

Any clue where I should look next?  

Thanks,
Pierre

PS  For years, I've run two instances of CM for different sets of
accounts -- that's why I mentioned the 2 versions above. When I restart
this instance which doesn't exhibit this problem, it will be at the newer
version...
