[Freeswitch-users] Event system overloading. Taking a 10 secondbreak

Wed Jan 25 23:37:02 MSK 2012

Thank you for your reply.

I use only external profile with:

<param name="manage-presence" value="false"/>

I use limit, for example:

<action application="limit" data="hash inbound ${destination_number} 1
!NORMAL_CIRCUIT_CONGESTION" />

The server handle media for some calls (1/3 of the total, the others are
with bypass_media=true) but the problem is not the number of total calls
because it can handle 5000 channels with media without issue.

The problem is present only when there are many session per second due to a
provider with low ASR (in this case there are many inbound calls due to
tries, more then 10.000.000 sessions per day).

About ethernet I don't know what can be the issue: the error seems to be
internal of the box, related to core freeswitch db. Any suggestion is very
appreciated.

I'll try with HEAD.

Stephen
