It was a fix for maxload during 4.2.x, but don't recall exactly when
was backported. Can you upgrade to latest 4.2.x and see the results?
Your config file and database don't require any change, only deploy
the binaries for latest 4.2.x and restart.<br>
<br>
If the issue is still there with latest 4.2.x, report here and I
will look at it with the first chance.<br>
<br>
Cheers,<br>

<div dir="ltr">I'm trying to set up kamailio
dispatcher to distribute calls to 2 asterisk
servers. So far, the failover case seems ok, but
I cannot get the dispatcher to distribute load.
All calls are going to the last destination
entry in the dispatcher table even if I have set
the maxload attributes. I'm using algorithm 10
for load distribution. The number of calls sent
to one asterisk is well above the maxload. Hope
someone more experienced in dispatcher can
review my config and give me some
recommendations. Thanks in advance.
