Very Slow delivery
« on: February 08, 2016, 12:49:20 pm »
Hi all!

I have implemented Zentyal 4.2.2 in a virtual machine (ESXi 5.5) with a CPU with 4 cores, 8 GB of memory and 400 GB disk.

The problem is that the delivery to local domain is very slow. Now there are more than 1,000 queued messages. Before we had qmail and we have never experienced these problems.

Per-Day Traffic Summary
    date          received  delivered   deferred    bounced     rejected
    --------------------------------------------------------------------
    Feb  8 2016     12967      22635        621         11        300

I think it's not a cpu or memory problem

I don´t see errors in the log files. Can you help me?

Howdy,

as far as I can see, the samba process has a hughe CPU load (93,9%) and aditionally a zombie process :-(

By now, I have no clue where this is comming from...

Regards

Thomas
