Hello,
PHP noob here. I've been working on writing a script (command-line) that
forks a number of children to do various tasks. I've been using
pcntl_waitpid inside a loop to wait for the children to exit, act on the
results, and fork another copy of the child. Where I seem to be running

Hi Peter,
If you can get it working can you send me a sample?
Certainly... database connections must be CLEAN! Meaning, you should
close them when they're no longer needed.
Additionally, each fork should open its own DB connection.
My completed code:

Sharing variables between processes and their forks needs something like
shmop or systemv shared memory.
Additionally, shared memory only lets you share basic variables and not
database resources... or as far as I understand.
So, each fork is required to create its own connection to the

Well, but I don't use multithreading? PHP is running as CLI exec, not
compiled into Apache...
That's my configure command:

Or do I have to care for thread safety anyway?

After some time however, the parent process hangs; apparently in
