 New Comment:

php7.2 - This seems to be related for us also, if a file that is read and removed in the same PID
proccess ends up with a nill pointer reference in memory the process crashes with the same Signal 7.
I can see this has been fixed in php7.4 but it would be nice if this could be back ported.
