Topic: Windows Apache Memory Issues

[tdellinger]

I have encountered a problem similar to what Razzi29 wrote about on Feb 6. At 2 of our customer sites, Apache kept increasing in memory usage, often exceeding 6 GB. Normally, our Apache servers use around 300 MB. I noticed that at the problem sites the amount just keeps increasing.

We are running Apache and PHP. I tried changing PHP versions thinking that would be the issue, but it didn't make a difference. So started testing with different versions of Apache and found that it appears to have started with Windows Apache version 2.4.55. 2.4.54 VS 16 and VS 17 seem to run OK.

Any thoughts?

Thanks!

Hi Tom,
do you run PHP as a module loaded in apache or over fcgid?

Hi James,

Thanks for the response, I am running PHP as an apache module. Should it be run using fcgid?

[James Blond]

On Windows PHP often tends to have memory leaks with extensions. There is a tutorial(1) how to change your setup to fcgid. You can run PHP as a module and over fcgid at the same time in different vhosts.

Also recommend to check try adding the following block at the end of httpd.conf

Thank you for the info, will try running php with fcgid.

Hi guys,

We have the same problem it seems.

Did running with fcgid solve your problem?

We have not yet installed the change to fcgid on a customers site (where the problem was occurring) since we wanted to ensure the functionality and performance would be OK using fcgid and it appears to be working ok at the moment with the older Apache.

We already have an fcgid program (mapserver) so want to make sure that both php and mapserver have the correct fcgid configurations.
