Further to my thread from a few weeks ago, this has started
happening on a second iPhone at the same site. Emails on this iPhone
have stopped syncing completely 4 days ago.
This time, after the hints from Michael J Rubinsky, I've taken a
closer look at the inbox of the affected account on a computer, and
the email immediately after the last message which has synced
successfully on the phone has the following subject line:
<<PR:63364>><<IR>> Site Inspection Report, Marshalswick, St Albans
There were 7 emails with this subject line - part of a thread. After
moving them away from the inbox to another folder, the sync resumed
instantly on the iPhone.
Is it possible that some characters in the subject line above trip
Horde, or the ActiveSync protocol somewhere? If I reconfigure the
iPhone to use imap, it syncs all messages of any type, without
complaints - so the issue seems to be somewhere between ActiveSync,
Horde and the Mail app on the phone.
It could be anything to do with those emails, could be some memory
limit being hit...could be lots of things. Unfortunately debugging
EAS stuff is tough. I really can't look more into it without either a
FULL activesync log - showing all the data, or copies of the emails
so I can try to replicate the issue locally. There are tons of
things that can trip up activesync clients and we try to catch most
of them (things like email headers with the wrong charset etc..).
Also, what version of PHP are you using?
I have just sent you one of the emails suspected to cause the
ActiveSync issue.
For the log - do I turn on ActiveSync logging per device - and send
you the log for this particular iPhone - or do you want a log
containing all the devices talking to the server?
Use per device logging and I only need that one device's log during the
time it issued a sync and retrieved the results that are failing. If
your version of horde has the option to enable "detailed" instead of
"protocol" logging for the activesync log, please enable that too (I
can't remember which version I introduced that in :)
Ok - will do. I am at this site this coming Friday - so I will get it
done then. And yes, I'm fairly sure the version of Horde there (latest)
has the detailed logging option for ActiveSync.
