Hi,
I finally took the time to diagnose that segfault I had, and I think it points to a serious bug in httpd. To summarize this: I don't receive window updates. In this specific test we set a very huge amount of small requests (bodies of 95 and 113 bytes), until we get out of the 65535 (or 65536) bytes of window space I get from httpd at the connection level. (Each stream doesn't get near its limit. I can try if I can receive window updates there. but currently I can't reproduce ever receiving a window update) Originally this caused a segfault in my code, but I fixed that one. But now I'm just stuck waiting to receive a window update from httpd. My last testing was against 2.4.x (to get the 2.4.18 goodness) Bert
