Re: [qmailtoaster] Re: Outlook goes offline

[Linux]

My Ram is ok. I want to add one important point here that, when I used my outlook on holiday ( only 2 to 3 people in office ) then it worked fine for a whole day. But when lots of people come to office then outlook start going in offline mode. Eric Shubert Tuesday, March 18, 2014 8:30 PM Check out this latest thread (New Build Issues) on the devel list: http://news.gmane.org/gmane.mail.qmail.toaster.devel We haven't determined recommended settings for dovecot on large hosts yet. EricB pointed out these links: http://wiki2.dovecot.org/LoginProcess http://wiki2.dovecot.org/Services I suspect that you're running up against the default_process_limit. Please let us know what you end up using for any settings you change. P.S. <rant on swap> I realize disk is cheap, but you've got way more swap than you need. The old rule of thumb of "swap should be 2x ram" isn't applicable to servers, especially these days. I usually use 256M or 512M for swap on a server. Also, it's much easier to manage swap using files instead of partitions. Not worth changing existing hosts, but something to keep in mind on new builds. </rant> Linux Tuesday, March 18, 2014 12:06 PM I am facing the same issue with TB.
