Message-ID: X-My-Opinion: War and bombs are bad. Peace and flowers are good. ;-D MIME-Version: 1.0 Content-Type: TEXT/PLAIN; charset=US-ASCII X-Spam-Rating: daedalus.apache.org 1.6.2 0/1000/N X-Spam-Rating: daedalus.apache.org 1.6.2 0/1000/N I'm experiencing hangs when testing out a application with tomcat 3.2.3 on Sun's JRE 1.3.1_01 running on a Intel 733MHz Redhat 7.1 stock kernel, using only 2 PoolTcpConnector HTTP (min/max spare = 0) connections, but with 150 clients, really hassling the server. The server hangs for quite some time, then it suddely starts working again. The load on the server drops to close to 0 and the java-threads disappear from "top" during these intervals. From my logs, it could look like it's managing about 30 requests, then chilling for about 30 seconds. Trying to go to the same site during this period also hangs my browser. With 3 threads, the rest is the same, this don't happen. I'm just wondering why it is like this, whether I should start bughunting in my application (synchs and the like), or just blame it on tomcat and/or java..! Any ideas? Thanks a lot! -- Mvh, Endre -- To unsubscribe, e-mail: For additional commands, e-mail:
