The defaults in the docs really cater to a low-traffic server; perhaps there should be a note to that effect.On Wed, 26 Oct 2022 at 01:47, Mike Dewhirst <mi...@dewhirst.com.au> wrote: On 26/10/2022 12:45 pm, Frank Gingras wrote:You could temporarily increase your ThreadsPerChild, as 25 is extremely low and increases the chances of that bug occurring.Thanks Frank These are the adjustments I made ...

This seems to have worked ... Server uptime: 1 day 17 hours 23 minutes 47 seconds Many thanks Frank Mike
The server is not heavily used other than by script-kiddies looking for php hacks. My next project is to find some way to black-hole anything with php or wp in the request. Maybe a redirect to google or something.I'd have to find out what fix applies to this bug, and why your installation is still vulnerable. Perhaps your distro used backports.I can't answer such questions. But the defaults were very restrictive originally - set by DigitalOcean I suppose. I changed them to the defaults specified in the Apache docs - per the comment lines in my original post. Thanks for responding so quickly.
