PHP PHPhasencounteredanAccessViolationat02C9A0F0 appears. how can this problem be solved?

PHP appears. PHPhasencounteredanAccessViolationat02C9A0F0 now there is a website submitting a form and this problem occurs. my environment is windows + phpphp: PHPVersion5.2.5. after submitting a form, the program will do the following. 1, verify that the form information is compliant with PHP has encountered an Access Violation at 02C9A0F0
This problem occurs when a website submits a form.

My environment is windows + php. The php Version is: PHP Version 5.2.5.

After submitting the form, the program will do the following: 1. verify whether the form information is standard; 2. soap calls an external program to verify the customer's insurance information.

This problem does not occur frequently. you can refresh it several times when it occurs. But what is the problem? what is the PHP eaccelerator problem found on the website? I don't have this in PHP. ini.

There is also a SESSION path problem. this is impossible. I have no problem logging in to the background, and I cannot use the SESSION to submit the form.

In addition, the permission for c:/winnt/temp is a problem. I put this environment variable in the folder because of security issues and grant all access permissions.

There is also a lack of memory, which is unlikely to happen. my server has 8 GB of memory and there are not many visitors to the new station.

I also removed the restriction set in the application pool.

Very depressing. please solve it. paste and copy it. thank you.
