Hi,

I am trying to confure FreeSwitch for my VOIP gateway.

It works really good in testing in low load.

However, whenever i try to increase load it takes only around 240 concurrent calls and any call beyond that it starts giving 503, Bad Gateway errors.

On console i start getting below error, which led me to believe that database issue and it seems it cannot take more connections. I tried setting up MySQL as database as well with same results.

2014-10-13 20:00:50.680811 [ERR] switch_core_sqldb.c:1196 SQL ERR: [select state,status,rpid,presence_id,uuid from sip_dialogs where uuid != '35579a26-4bc4-40ab-ae5c-a2b6f460c801' and call_info_state != 'seized' and hostname='BOX02' and profile_name='internal' and ((sip_from_user='sipp' and sip_from_host='10.0.0.14') or presence_id='sipp@10.0.0.14') order by rcd desc] unable to open database file
