New Comment:
My previous comment about the plimit workround does not seem to be working
consistently. It worked for about 10 minutes and then I ran into problems
again. The process forks are only happening once or twice a minute. So it's
not that the new range for FD was used up within 10 minutes.
The only thing that seems to work is waiting a few minutes.

This works for me. php running within Apache (process name "httpd").
sudo plimit -n 65536,1048575 $(pgrep 'httpd')
This increases the integer values allowed for new file descriptors.

Tune your Solaris instead.
Values of rlim_fd_max and rlim_fd_cur can be changed with appropriate settings
in /etc/system.
I doubt that PHP can implement any workaround for OS limit.

Description:
------------
Solaris restricts the use of popen() to 255 files, which is a low limit in case
of servers. When using PHP's system() commands, PHP calls Solaris popen(). This
fails, when too system-commands have been invoked.
See here (http://www.sitepoint.com/forums/showthread.php?p=1245879#post1245879)
for more details.
Expected result:
----------------
PHP should implement a workaround or call another Solaris function for invoking
system commands.
