Hello,

I use mod_proxy_ajp with keepalive connection.

When the client continued to request to the connection,
RSS of httpd has increased by 16 Kbytes per minute.

I found a memory leak in proxy_ajp_handler.
And I found r707163 in trunk too.

I attach a patch what I made based on r707163.
I confirmed that the memory leak is fixed by this patch.
Therefore, we should merge this fix to proxy_ajp_handler.

Please check my patch.

Regards,
Naohiro Ooiwa

Hi all

I tried to request stress test on the one session to the apache.
The memory leak of about 600 Kbytes per second had occurred.

And I tried to use mod_jk instead of mod_proxy_ajp.
In this case, the memory leak didn't happen.

Regards,
Naohiro Ooiwa

fixed in trunk r1334343

Ported back to 2.4 as r1368450.
Released with 2.4.3.
Should probably be ported back to 2.2 as well.
