Searching the net has led me here: https://lists.kamailio.org/pipermail/sr-users/2018-January/099881.html It looks like Kamailio cannot parse HTTP responses, but that message is ambigous. Why would it try to parse them in the first place? ``` 32(203) ERROR: <core> [core/parser/msg_parser.c:748]: parse_msg(): ERROR: parse_msg: message=<HTTP/1.1 100 Continue ``` ``` 47(89) ERROR: <core> [core/parser/msg_parser.c:681]: parse_msg(): ERROR: parse_msg: message=<HTTP/1.1 101 Switching Protocols ``` <!-- Explain what you did, what you expected to happen, and what actually happened. --> ### Troubleshooting Except confirming that the messages are legit, there is nothing else that I can do. #### Reproduction <!-- If the issue can be reproduced, describe how it can be done. --> The first error is generated by making HTTP requests using the HTTP client embedded in Kamailio. The second error happens on each WebRTC call served by Kamailio. #### Debugging Data <!-- If you got a core dump, use gdb to extract troubleshooting data - full backtrace, local variables and the list of the code at the issue location. gdb /path/to/kamailio /path/to/corefile bt full info locals list If you are familiar with gdb, feel free to attach more of what you consider to be relevant. --> ``` (paste your debugging data here) ``` #### Log Messages <!-- Check the syslog file and if there are relevant log messages printed by Kamailio, add them next, or attach to issue, or provide a link to download them (e.g., to a pastebin site). --> ``` (paste your log messages here) ``` #### SIP Traffic <!-- If the issue is exposed by processing specific SIP messages, grab them with ngrep or save in a pcap file, then add them next, or attach to issue, or provide a link to download them (e.g., to a pastebin site). --> ``` (paste your sip traffic here) ``` ### Possible Solutions <!-- If you found a solution or workaround for the issue, describe it. Ideally, provide a pull request with a fix. --> HTTP responses should not go through the core message parser. Not sure if this can be described as a "solution". ### Additional Information * **Kamailio Version** - output of `kamailio -v` For the 100 parsing error. The used HTTP clients are `http_client` and `http_async_client` modules. ``` # kamailio -v version: kamailio 5.5.4 (x86_64/linux) flags: USE_TCP, USE_TLS, USE_SCTP, TLS_HOOKS, USE_RAW_SOCKS, DISABLE_NAGLE, USE_MCAST, DNS_IP_HACK, SHM_MMAP, PKG_MALLOC, Q_MALLOC, F_MALLOC, TLSF_MALLOC, DBG_SR_MEMORY, USE_FUTEX, FAST_LOCK-ADAPTIVE_WAIT, USE_DNS_CACHE, USE_DNS_FAILOVER, USE_NAPTR, USE_DST_BLOCKLIST, HAVE_RESOLV_RES, TLS_PTHREAD_MUTEX_SHARED ADAPTIVE_WAIT_LOOPS 1024, MAX_RECV_BUFFER_SIZE 262144, MAX_URI_SIZE 1024, BUF_SIZE 65535, DEFAULT PKG_SIZE 8MB poll method support: poll, epoll_lt, epoll_et, sigio_rt, select. id: unknown compiled with gcc 8.3.0 ``` For the 101 parsing error.
