Crashes in mediasoup (get a core dump)

If you get a crash in mediasoup server, this is, if you get an error log as follows:

2020-01-06T16:02:57.965Z mediasoup:ERROR:Worker worker process died unexpectedly [pid:22, code:null, signal:SIGABRT]

or if the worker.on("died") event fires, this is a bug in mediasoup that should not happen.

If so, please report the issue in GitHub and also enable core dumps in your host.

Enabling core dumps in Linux

If you run mediasoup in Linux, do the following before running your mediasoup application again:

$ mkdir /tmp/cores
$ chmod 777 /tmp/cores
$ echo "/tmp/cores/core.%e.sig%s.%p" > /proc/sys/kernel/core_pattern
$ ulimit -c unlimited

Then run your mediasoup application. If the crash happens again you should get a core dump in the /tmp/cores folder. Open it with gdb and attach it into the issue reported in GitHub:

$ gdb PATH_TO_YOUR_NODE_APP/node_modules/mediasoup/worker/out/Release/mediasoup-worker PATH_TO_COREFILE

Then, within the gdb terminal:

gdb> bt full
Enabling core dumps in OSX

Crashing processes in OSX automatically got a crash report in /Users/USER/Library/Logs/DiagnosticReports folder.

Forcing a core dump or crash report

You can check whether your setup works by manually generating one as follows:

$ pidof mediasoup-worker
46717 46718 46719 46720

$ kill -s SIGSEGV 46717

Then check the generated core dump or crash report file in the corresponding folder.
