[SR-Users] random incorrect method parsing

Hi folk! Have a strange issue, and cannot understand what is wrong. Test scheme UA(sip) -> INVITE -> Kamailio The transport protocol used is TCP. The issue is reproduced randomly, in case of wrong INVITE, Kamailio does not parse Method from R-URI and answer "400 CSeq method does not match request method". The log with debug level 3 for such INVITE: https://gist.github.com/vance-od/c4e1c783adba02d80c58 my first confuse is why in line 2 different number of bytes: "read= 1025 bytes, parsed=1037" the second is in line 12: Method value is empty after this everithing brokes and kamailio answers 400. Just another call: the same setup (same device, kamailio instance etc), same conditions, just another call. Everything is OK, similar part for good call: https://gist.github.com/vance-od/01b5dff2d81f0878cff4 All my attempts to find the diff between to messages goes to nothing, the 2 INVITEs looks similar, the wireshark analyse of TCP level - also had no result (all is similar) The issue happens only with one of our devices and only in case of TCP/TLS (UDP constantly ok, this is why I am assured the problem is in device, but I need proofs) version: kamailio 4.2.5 (i386/linux) flags: STATS: Off, EXTRA_DEBUG, USE_TCP, USE_TLS, TLS_HOOKS, USE_RAW_SOCKS, DISABLE_NAGLE, USE_MCAST, DNS_IP_HACK, SHM_MEM, SHM_MMAP, PKG_MALLOC, F_MALLOC, DBG_F_MALLOC, USE_FUTEX, FAST_LOCK-ADAPTIVE_WAIT, USE_DNS_CACHE, USE_DNS_FAILOVER, USE_NAPTR, USE_DST_BLACKLIST, HAVE_RESOLV_RES ADAPTIVE_WAIT_LOOPS=1024, MAX_RECV_BUFFER_SIZE 262144, MAX_LISTEN 16, MAX_URI_SIZE 1024, BUF_SIZE 65535, DEFAULT PKG_SIZE 8MB poll method support: poll, epoll_lt, epoll_et, sigio_rt, select. will appreciate any help or idea ,with such a mess!
