Re: [SR-Users] Kamailio 4.4.4 crash in tcp_read_headers()

Hello, I see port is 5060, is it a possibility that you have multiplexing of websocket or other protocol (http, msrp) there? Can you also give the locals? frame 0 info locals Cheers, Daniel On 05.06.17 05:19, Armen Babikyan wrote: Hello, Over the past few months, I've seen a smattering of kamailio crashes on various systems with identical backtraces: SIGSEGV in tcp_read_headers(), at tcp_read.c line 628. Example here: https://pastebin.com/qJ3ypnVz Note that in frame 0, print *c shows that req->parsed is pointing to an address exactly 8GB lower than req->buf. That req->parsed is pointing to an invalid memory location, crashing kamailio when the location is dereferenced. In other coredumps, I see that req->parsed is pointing to an address exactly 4GB lower than req->buf. Other info: This is Kamailio 4.4.4 on x86_64. I've not had success trying to reproduce this yet. Also worth noting that the crashes seem to be consistently associated with processing traffic from a UA connected over SIP/TCP; I've seen no other transport associated with this crash. Thoughts are welcome. Thanks!
