Hi Francis,

I had stabillity Problems in a virtual environment. Also the seemingly comsumption of all memory could be due to the characteristic linux memory management to use all free memory as cache. Especially if you use the server also as a file server and copy data. With the command free -m you can check how much of your memory is really used, and which amount is used for data caching.

Otherwise it would be helpfull if you gave a little more information about your installation.

Kind regards, Jens.

Hi Francis,

We are not using activesync. Because we thought about activesync at first, we
removed it explicitly.
I wrote the line in the config, but restarting the service shows
"/etc/default/sogo: line 5: SoGoDebugRequests: command not found“
(I tried different spellings as well)

We have PREFORK=10 in our sogo.conf. Which is also the only setting we
modified (and the only entry in our sogo.conf).
`ps aux | grep sogo` shows 11 Processes. Which is expected.

The machine has 6GB of RAM, which should be plenty for 10 Processes with
384MB each (this is, what sogo says, when its starting up).

Thanks for your help!

I have a strange problem, where SoGo starts to use up all memory (currently
6GB) which then crashes the whole server. I can’t find any directly related
entry in the logs, however I see a lot PROPFIND from the same IP, just before
it stops.

The last log entry before the crash is always just some random operation, the
next entry is
Mar 02 09:34:16 sogod [1295]: version 2.2.16 (build @shiva.inverse
201502121302) — starting

This happens roughly once per day, at seemingly random times. The only thing
left to do, if this happens, is power-cycling the server.

Any tips, how I can debug this further? Or has anybody experienced the same
Are you using ActiveSync? If so, what is the average number of clients that
connect to your server simultaneously?

Do you have any slow queries (LDAP/SQL)? You can set SOGoDebugRequests = YES
to get some timings.

How many sogod processes do you have? Can you share your sogo.conf?
