Hey All, We are load testing Kamailio 4.2.3 and we are seeing the waiting within the transaction manager increasing. I’ve increased the children from 8 to 16 to 24, but we are still seeing a large amount of waiting. I don’t see an errors in the logs. Can anyone give me a clue on where to look. 05-02-18_03:07:38 PM tm.stats { current: 390 waiting: 226 total: 2361 total_local: 0 replied_locally: 1406 6xx: 0 5xx: 0 4xx: 88 3xx: 0 2xx: 3180 created: 2361 freed: 1971 delayed_free: 0 } Mack Hendricks / Head of Support / dOpenSource web: http://dopensource.com <http://dopensource.com/> support: +888-907-2085 dSIPRouter <http://dsiprouter.org/> - GUI focused on implementing Kamailio to provide SIP Trunking and PBX Hosting Services
