Hi,
i have some sogod processes eating very much memory. I suspect those are
Active Sync processes trying to initially sync to Outlook 2013 (and
failing), specifically with large mailboxes. One for instance is about
5GB. On mobile phones, Active sync works, perhaps because they sync only
the last few weeks of mail and not everything.
Even with only 2 Outlook Active Sync users there are four sogod
processes using more than 1 GB of memory:

When the kernel runs out of memory, sogod processes get killed:

Does anybody know how to configure sogo that Active Sync with Outlook
2013 works with large mailboxes (small mailboxes work)?
sogo 2.3.2, cyrus 2.4.17 on Ubuntu 14.04
Thank you.
