Hi try run mediasoup with: ```auto export MEDIASOUP_USE_VALGRIND="true" export MEDIASOUP_VALGRIND_OPTIONS="--leak-check=full --track-fds=yes --log-file=/tmp/mediasoup_valgrind_`data +%s`.log" ``` but workers crash: ```auto 0|edge | (node:60084) UnhandledPromiseRejectionWarning: Error: [pid:60095, code:1, signal:null] 0|edge | at ChildProcess. (/home/ubuntu/edge/node_modules/mediasoup/lib/Worker.js:122:43) 0|edge | at ChildProcess.emit (events.js:376:20) 0|edge | at Process.ChildProcess._handle.onexit (internal/child_process.js:277:12) 0|edge | (Use `node --trace-warnings ...` to show where the warning was created) 0|edge | (node:60084) UnhandledPromiseRejectionWarning: Unhandled promise rejection. This error originated either by throwing inside of an async function without a catch block, or by rejecting a promise which was not handled with .catch(). To terminate the node process on unhandled promise rejection, use the CLI flag `--unhandled-rejections=strict` (see https://nodejs.org/api/cli.html#cli_unhandled_rejections_mode).

Do you have valgrind installed though? It looks like the process has crashed and no one handled an exception that was thrown.
