Kolab community version recommendation?

[Klaus Vink Slott]

Any news on when?

A month or more ago I did a little testing on Kolab16 and if found it quite
useable. I found some guide for Fedora 23 and got it up and running smoothly.
I had the web interface up and running and poked a little around in it.

Then I had to attend to other matters, so I forgot about it for a week. I then
returned, booted the vm and did a dnf upgrade. After that i could no longer
connect to the kolab web service. (white page).

I then decided to ditch my install until Kolab 16 became stable.
I have regularly checked back on the download page but there is still no sign
that Q2 2016 has ended :-)

My mail server is used by a couple of small local nonprofit organizations so
stability is crucial. We do have a stable mail service running (postfix+
dovecut) and not in a hurry, so what do the Kolab community suggest?

Should I just wait a little more as Kolab 16 is soon to be released..

Should I install an migrate to Kolab 16 on a Centos as that is reliable enough

Should I migrate to Kolab 14 as the update to Kolab 16 will not be
recommended for the next many months - and the update will be a walk in the
park anyway.

Hi,
AFAIK Kolab 16 is stable. However, I experienced a similar bug to you: I
installed a new Kolab version on Debian Jessie and the webserver
(apache) quit working after a while. This happend due to some default
configuration - I forgot which one - but you'll find out in the List
archives.

Best Regards,
Hermann

This sad bug is having a very long history and has something to do with
how SWIG (a php module framework) is not able to unload the libkolab
stuff correctly.

Your crash happens because logrotate tries to reload the apache (which
crashes the swig plugin during unload/load.

If you adjust the logrotate apache2 script to restart instead of
reload your apache should be fine (until something or someone reloads
Apache).

IMO I personally prefer the use of php-fpm together with nginx (you
could also use apache in that case). If you split php from apache you
won't expire any of those hang issues but it requires more configuration
and customization work.

You can consider Kolab:16 as the Stable version. There might be a few
smaller bug or stability updates but overall it looks okay. A few Debian
Updates to get Jessie more stable are on it's way and should land soon.

If you check out kanarips message I would choose either CentOS 7
(primary) or Debian 8 (in a few days) as a stable platform to start and
work with. Distributions like Ubuntu, Fedora and others might work but
could need more help from the community to get packages work correctly. I
personally would consider one of the recommended distributions.

Thank you all for you input.

I have decided to make a fresh Kolab16 install on one of the recommended
platforms. Most likely CentOS 7.

If that was my problem to - I would have thought that the problem would
gone after a reboot.

Thanks for recommendation, nginx and php-fpm is also my preferred
platform. I may look into that later, when I am more comfortable with Kolab

If stability is crucial, you should seriously consider a software subscription
for services you provide, see https://kolabenterprise.com/benefits
