php problem executing command in background

[esmith]

I have a webserver (apache 1.3.27, php 4.2.3) running on my SL6000L, and I'm having trouble executing commands in the background.  When I execute a command in the background using any of the techniques from php.net, the current page loads, but the next page won't load (session_start() blocks until the background command is complete).

Any suggestions?

I've tried forking, calling scripts, session_write_close(), but nothing seems to work.

Thanks in advance, esmith

Solved the problem, it was a php thing.  I had to execute session_write_close() before starting the background application
