In short on base of above mentioned Astxx, i have compiled .dll for third party windows application 1C, I also tried compile the same .dll on pure WinSock2 in both cases memory leak presents. Active using AMI with 4 clients, increase RAM buffer for ~3 hours from ~8400 kb to ~20000 kb, below you can see details:

then registered trunk, registered peer, connect and login AMI manager, and now we have
Mem: 1030584 166372 864212 0 8444 89616
it's OK, and now trying to send CLI over AMI
sent CLI command: core show settings

as we see recieving messages over AMI also inrease RAM buffer
now sent CLI command: sip show peers

> Calling CLI commands through AMI interface causes memory leak (sending AMI actions does not cause leak), each call CLI command through AMI increase RAM buffer by 8 kb. I am using Astxx lib (by Matthew A. Nicholson http://matt-land.com/astxx/) as AMI caller, memory usage increases when executed
