terminate of uas on connection reset by peer ( sipp 3.7.2 )

[gitkoyot]

Hi,
I have a scenario where under certain conditions server sends invite toward uas script, but due to timeouts it resets the connection. The whole UAS part of sipp terminates.
when socket on server is closed normally the issue does not appear (it reports endpoint not connected, but it does not terminate sipp).

I attached simple *.c program that simulates this.
I am running standard uas script:
sipp -sf ./uas.xml -t 'tn' -p 5060 -recv_timeout 5000 -send_timeout 5000

here is the stack trace

when I comment out linger option in reset.c file - sipp does not terminate.
