Memory leak on master #5042
Description
I just pulled down a fresh copy of master, did nothing special:
autoreconf -i
./configure --prefix=/tmp/ats
make -j12 && make install
/tmp/ats/bin/traffic_server
ab -n 10000000 -c 1000 http://127.0.0.1:8080/
I made no changes to any config files other to to enable the memory debug output every 30 seconds to see where it was going. And the memory stats are below, but basically it looks like Http1 client session allocators are leaking pretty badly.
