Net, it can't do anything useful without r-user. This short-circuit should be possible well before the problematic functions you mention. OK, I'll look at adding the same !r-user test, unless others think it's unnecessary. It looks like it might be necessary to me, but I'm not 100% sure.

The logic should flow like this: H I'm not seeing it in trunk.

The logic should flow like this: H I'm not seeing it in trunk. The code Graham is talking about was introduced by him in r93811 and was removed in r104602 about 4 years ago. So I am not astonished any longer that I cannot remember this optimization. It was before my time :-). This optimization was never in 2.2.x (2.0.x still ships with it). BTW: This logic flow cannot be restored easily, because due to the current pool and bucket allocator usage it *must* be ensured that all buckets are flushed down the chain before we can return the backend connection to the connection pool. By the time this was removed and in 2.0.x we do *not* use a connection pool for backend connections. Regards Rüdiger
leak on graceful restarts
Looking at a problem that seems easy to re-produce using un-patched trunk, 2.2.10 and 2.0.63. Using a graceful restart causes higher memory usage in the parent, which is then passed on to the 'new' children processes. The issue seems to appear in all the Worker, Event and Prefork MPMs. Compile up httpd without apr pool debugging enabled, start it as normal, and then check the memory usage: $ ./apachectl start $ ps alx | grep 18459 1 1000 18459 1 20 0 152752 2672 674009 Ss ? 0:00 /home/chip/temp/httpd/bin/httpd -k start $ ./apachectl graceful $ ps alx | grep 18459 1 1000 18459 1 20 0 152752 3192 674009 Ss ? 0:00 /home/chip/temp/httpd/bin/httpd -k start $ ./apachectl graceful $ ps alx | grep 18459 1 1000 18459 1 20 0 152752 3236 674009 Ss ? 0:00 /home/chip/temp/httpd/bin/httpd -k start $ ./apachectl graceful $ ps alx | grep 18459 1 1000 18459 1 20 0 152752 3280 674009 Ss ? 0:00 /home/chip/temp/httpd/bin/httpd -k start (2672 - 3192 - 3236 - 3280) And, at least over here, httpd consistently grows in RSS, without any obvious cause. Seems reproducible on Ubuntu and Darwin, using 2.2.10, 2.0.63 and trunk. Any ideas? Thanks, Paul
