Hello, I have Kamailio 5.1.4 (from deb.kamailio.org) running on a Debian 9 AMD64 VM with 1 CPU and 1G of RAM on ESXi.  For KEMI I am using the liblua5.1-0:amd64 package, version 5.1.5-8.1+b2. The configuration is rather simple - dispatcher module reading the gateways from a file and forwarding everything to them based on a custom variable. There are 2 gateways in the file being pinged with OPTIONS packets every 10 seconds. Only a single SIP user is connecting to the machine (besides the occasional scanner). I can post the config if necessary, but I don't think that is the issue (see below). The crash has happened twice already - once on 2018-08-07 19:45 and 2018-08-08 14:33 EEST. You can find an excerpt from the Kamailio debug log at https://paste.fedoraproject.org/paste/bvyUMj3s5g2CcBN3JSBt5A/raw. As you can see, it crashes when trying to run the Lua route on an incoming packet. I am assuming the problem is this: Aug  8 14:33:14 lb-dev1 kamailio[13209]: *** Error in `/usr/sbin/kamailio': realloc(): invalid next size: 0x00005573dbff1ef0 *** However, I could not find any (direct) `realloc()` calls in the source for app_lua, so maybe this is an issue somehwere in liblua... Thoughts? Ivaylo _______________________________________________ Kamailio (SER) - Users Mailing List sr-users(a)lists.kamailio.org https://lists.kamailio.org/cgi-bin/mailman/listinfo/sr-users
