Summary: | 0000334: apache1 keepalives broken by JNI extensions | ||||
Description: |
RSN-378 When the JNI extension (libresin_os.so) is being used, apache1 mod_caucho connections are being closed immediately after each request, ignoring any keepalive and client-live-time configuration. This has rendered Resin 3 unusable on high-load servers routing requests through apache1. I devised a simple test to confirm that connections are being closed immediately: I make 100 synchronous requests to Apache 1.3 (with MaxClients 4). With my previous Resin 2 setup, 4 connections are ESTABLISHED and reused between the apache processes and Resin. With Resin 3, I get 100 closed (TIME_WAIT) connections (between mod_caucho and Resin, not counting the closed apache request connections). I have tried tweaking several parameters including keepalive-max, keepalive-timeout (which appears to be ignored in the source code), client-live-time, and client-read-timeout, with no luck. When I removed libresin_os.so from Resin's LD_LIBRARY_PATH, connections behave as they did with Resin 2. |
