2.4.12 & 2.4.13 memory leak?

[nono303]

Hi @icing, I've just noticed strange httpd memory usage (Windows - httpd 2.4.53 x64 vs17) with latest mod_md:

1) 2.4.11 2) bump to 2.4.12 3) rollback to 2.4.11 4) bump to 2.4.13

Is there any major change that can imply a memory leak since 2.4.12? I'll try to provide additional information - if needed - but it will be Windows related....

Hmm, the changes between 2.4.11 and 2.4.12 were related to the server-status information.

How many managed domains do you have?

How many managed domains do you have?

20

Do you monitor server-status regularly? or have you enabled it at all?

[nono303]

Yes, i GET /server-status?auto every minute. I think the leak is not related to "other" httpd usage as i can't see correlation with busy workers I just made a full dump of process but i'll have to find how to analyse it...

[icing]

Hmm, running some local test with a million requests to server-status and the memory of the process keeps increasing. Something smells...

[icing]

Think I found it. Was a wrong reference counting in the JSON code. That was triggered mainly by server-status.

I'll make a release soon for you to verify.

Please give v2.4.14 a try.
