Hello,
I am running a mail server with horde and have ActiveSync enabled.
Clients connecting to ActiveSync are MS Outlook 2016 clients. I think I
am running into a bug for various reasons:
- Horde is running fine, all but one mailboxes work perfectly over
ActiveSync
- Only one Mailbox does not work over ActiveSync
- On a fresh client (Outlook 2016) mailbox, sync will start and than
hang after a few messages being synced
- CPU usage spikes to 99% and I get this error message in apache log:
Fatal error: Allowed memory size of 268435456 bytes exhausted (tried to
allocate 72 bytes) in /usr/share/php/Math/BigInteger.php on line 1089
(full stack trace below)
So my guess is: there must be an offending message which causes
ActiveSync to hang on that line. What do you think? Should I submit a
bug report?
Another question: I'd like to apply a quick fix in order to get the
customer's Outlook up and running. My idea is to var_dump some
information into a temporary file, identify that message and move that
message out of the way in order to be able to proceed. So where should I
hook into this chain (see call stack below)?
Any help would be highly appreciated. I am running the latest version of
Horde on a fully updated ubuntu 16 with apache.
Thank you for your attention
Wolfgang
