Hi,

I started having issues with my server on Monday... the server  is very slow during working hours and the services even if they show that they are running properly the email clients cannot connect to the server or if they are connecting they are  not getting updated... after restart everything is ok for about 5 min... Before I had no issues... Do you have any idea why do I have these problems?

Thx

Re: Server very Slow

*) Please check Postfix log file first, did your server very busy to send out many emails?
*) Run 'top' command, which program uses most CPU/Memory?

Did you upgrade SOGo to the latest version? If not, please upgrade it first. Let's see whether the latest version fixes this issue.

Re: Server very Slow

Hi Zhang,

I switched SOGo 2.xx apt repositories to nightly builds in /etc/apt/sources.list (deb https://packages.inverse.ca/SOGo/nightly/2/ubuntu/ trusty trusty)

sudo apt-get update

sudo apt-get dist-upgrade

sudo apt-get autoremove

Problem is Fixed...

Thx for your help!
