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

I'm already using the ramdisk.
The problem happens when I have a provider that give congestion.
In this case Freeswitch receives many tries but few connected calls and the
number of session per second is high.
To avoid the "event system overloading" (avoiding to lower the global
session per second 'sps' parameter) I have insert in dialplan:

<condition field="destination_number" expression="^2519(.+)$" break="never">
    <action application="limit" data="hash inbound ETHIOPIA 10/1
!NORMAL_CIRCUIT_CONGESTION" />
</condition>

In this way I have limited the session rate for the congestioned
destination where I have so many tries.

My dubt remain: I have ramdisk, I have many idle cycles on cpu, the usage
of disk is near zero (dstat) why I cannot handle this session rate?
