This might be a client bug, but I hope Horde could handle it better.

In the last few days we had several webserver processes caught in an  
infinite loop, because a client sent an unknown sync option. These are  
the last lines, the full log is attached:

2014-07-29T14:52:51+02:00 DEBUG: [21666] I    <Folder>
2014-07-29T14:52:51+02:00 DEBUG: [21666] I     <SyncKey>
2014-07-29T14:52:51+02:00 DEBUG: [21666] I       0
2014-07-29T14:52:51+02:00 DEBUG: [21666] I     </SyncKey>
2014-07-29T14:52:51+02:00 DEBUG: [21666] I     <FolderId>
2014-07-29T14:52:51+02:00 DEBUG: [21666] I       @Contacts@
2014-07-29T14:52:51+02:00 DEBUG: [21666] I     </FolderId>
2014-07-29T14:52:51+02:00 DEBUG: [21666] I     <Options>
2014-07-29T14:52:51+02:00 DEBUG: [21666] I      <>

The loop is in Horde_ActiveSync_Request_Sync::_parseSyncOptions, line 1090.

I can try to capture the traffic in the next days if you are  
interested, but he is currently not online. The user agent is  
WindowsMail/17.5.9600.20498.
