Only 6 scripts can run simultaneusly

pianoparadise

I am running a php script that does data manipulation on a mysql database with 1 million rows. Since there are so many rows, I broke it up so multiple scripts (10) could be run simultaneously each operating on 100,000 rows.

When I try to run more than 6 though, the 7th script stalls like it has been placed in a queue. It does not seem like a memory or cpu power issue. Is there any way of fixing this by changing a configuration option in apache? I am using Xampp with Windows 7.

dagon

are you using PCNTL functions?(if not you should be) Can you post the code.

I'm not using those functions since I have xampp on Windows 7, and as far as I know it only works on unix servers. I also tried using curl for parallelism, but wasn't too fond of it. What are the best alternatives I can use?

No part of that suggests why Apache is even in the loop.

So... why are you using Apache at all, and how is it involved?

EDIT: Also note that you might say what browser you're using. Note that IE has a max number of 6 concurrent connections per host. Other browsers have similar limits.
