Hello,
I'd like to know if anyone of you is finding my same problems using any
recent asterisk version, after 13.7 / 13.8  with chan_sip.

If I use any recent asterisk version, after just few seconds asterisk
completely locks up, stopping processing SIP/UDP packets. Nothing is
written in the asterisk log, but if I run "netstat -nap | grep 5060" I
see the UDP buffer filled up.

If I step back to asterisk 13.2, then all is fine and asterisk is rock
solid.

I know I should use PJSIP and chan_sip is no more supported, but at this
point, if this is the working state of chan_sip, it should be completely
removed.

It's not the normal working state of chan_sip, in fact it hasn't really been touched in any way that would cause this to happen and I haven't seen any bug reports along these lines. I also know that FreePBX is running both chan_sip and chan_pjsip and haven't experienced anything so it may be isolated to you. If you follow the instructions on the wiki[1] it will provide a backtrace which will show where chan_sip is hanging.
