I'm testing this external app (cgrates, you all know it) that talks to Kamailio via evapi. 

Every n minutes the app sends an evapi request to Kamailio which returns back the list of all dialogs like so:

\"jsonrpl_body\":$jsonrpl(body)}");

The problem is that the size of $jsonrpl(body) PV is limited by Kamailio's pv_buffer_size setting.

My math shows that a single dialog is about 1KiB of json data.

Problem: Kamailio fails to start with a pv_buffer_size higher than 117 KiB (119808 bytes), which in turn rends the system's limit to about 117 simultaneous calls... pretty sad.

Below find the error when trying to start Kamailio with higher values:

 0(17080) ERROR: <core> [core/mem/q_malloc.c:291]: qm_find_free(): qm_find_free(0x7f02275c5010, 120832); Free fragment not found!

 0(17080) ERROR: <core> [core/pvapi.c:2072]: pv_init_buffer(): cannot init PV print buffer slot[39]

Is there a workaround for this?

Thanks,
