You just run out of filedescriptors. This is not something PHP can fix for you. You either need to cut down in the number of Open files, or adjust your kernel parameters.

Ahh, no I didn't.  I have more then enough file descriptors but PHP is not using them.

[root@ozhlin01 root]# cat /proc/sys/fs/file-max
32768

I suspect it is hard coding it's max number of file handles?

Please note I opened this ticket at the suggestion of Wez Furlong.  Please also take a look at the following:

We've just been using hacky workarounds for this which I doubt anyone really wants in the 4.3.x tree.  Wez has fixed all such problems properly in 5.0.3 so the proper solution lies there.

Assigning to Wez then, if he would be so nice to fix this in 4.3.x branch too. :)

I don't have the time to back-port the patch, which is why I suggested opening up this bug report.

It works in PHP 5 so use PHP 5.
