Random failures when forking a process

[srjlewis]

Hi

I am getting random failures when forking a process.

It shows as a Couchbase\Exception\AmbiguousTimeoutException or a Couchbase\Exception\UnambiguousTimeoutException in the client or parent.

The test script being used is here

This is a example of a parent failing link

Most of the other workflow jobs are showing child failures link

The tests are using the following matrix

 matrix:
  operating-system: [ubuntu-latest]
  php-versions: ['8.3', '8.4']
  ext-versions: ['couchbase-4.2.2', 'couchbase-4.2.3', 'couchbase-4.2.4', 'couchbase']

I am also seing it fail on MacOS aarch64
