Intermittent crashes when running unity builds on docker.

Bug description

We are previously running our Unity CI builds on Windows, and wanted to run them in an isolated docker container environment for security reasons. The unity version is 2021.3.21f1 and we tried to set up under Ubuntu 22.04. The GameCI image tested is ubuntu-2021.3.21f1-webgl-3.0.1 and our own Dockerfile based on the Dockerfile by GameCI. We had only edited the file to support multiple modules. Unfortunately, we get two errors below occasionally, about an error every 3 or 4 runs.

Aborted (core dumped)

The second (separate) error we occasionally get is:

An error occurred while resolving packages:
  One or more packages could not be added to the local file system:
    com.unity.burst: aborted

A re-import of the project may be required to fix the issue or a manual modification of ./Packages/manifest.json file.
/home/bokken/build/output/unity/unity/External/baselib/builds/Include/C/Internal/Baselib_Semaphore_FutexBased.inl.h(151): Assertion failed (count >= 0) - Destruction is not allowed when there are still threads waiting on the semaphore.

To try to fix the error, we set vm.max_map_count and kernel.sem on both the build machine and docker container. But it still meets the errors above. Script to set sysctl:

memorymaps=$(cat /proc/sys/vm/max_map_count)
echo "max_map_count:" $memorymaps
if [ $memorymaps -le 100000 ]; then
    echo "memory maps less than 100000. updating config."
    sysctl -w vm.max_map_count=262144
fi
semaphoreconfig=$(cat /proc/sys/kernel/sem)
semaphoreconfig=( $semaphoreconfig ) # expand into array
echo "sem:" ${semaphoreconfig[0]} ${semaphoreconfig[1]} ${semaphoreconfig[2]} ${semaphoreconfig[3]}
if [ ${semaphoreconfig[0]} -le 50000 ]; then
    echo "semaphore config less than 50000. updating config."
    sysctl -w kernel.sem="50100 128256000 50100 2560"
fi

Expected behavior

The build should be succeeding 100% of the time, but errors out 30% of the time.
