Hi, I'm getting stuck with an error we are seeing on our production server under load.
I've googled and found many posts on similar topics but I haven't found an answer yet, I was hoping somebody here could shed some light on my issue: We upgraded our combination of Apache,Tomcat,Java all running on Solaris 10 to Apache 2_2.0.55.build2 Tomcat 5.5.23 Java 1.5.0_06-b05 Our Apache Tomcat connector is AJP/1.3. It's all installed on the same server, we have no tomcat clusters and no load balancers. With a few (10) concurrent users accessing the various JSP's everything worked as expected, all our functional tests passed. We opened more up live traffic to the server and starting seeing the following error message: [Thu Sep 06 02:23:00 2007] [error] ajp_service::jk_ajp_common.c (1758): Error connecting to tomcat. Tomcat is probably not started or is listening on the wrong port. worker=worker1 failed On the client side this was being reported as a 503 and our "intelligent" browser was re-submitting the request and generally, on the second time, the request would be successful. After an hour we then had a Solaris panic, and after analyzing the crash using scat I can see that the cause was: panic string: BAD TRAP: type=9 rp=2a1015332d0 addr=0 mmu_fsr=0 and looking further into the trap, it seems to be network related. <trap>ip:tcp_conn_request+0x894 (0x4, 0x2000, 0x136ec00, 0x3a2b9a44040, 0x40e03960300, 0x40dedc247c0) ip:squeue_drain+0xe4 (0x300015ddec0, 0x40e2021c1c0, 0x411666de, 0x135f2c0, 0x3a2b9a44040, 0x3) ip:squeue_enter+0x358 (0x300015ddec0, 0x38fca5e0d80, 0x3000426b640, 0x3a2bd674c00, 0x0, 0x1) ip:tcp_wput - frame recycled I am still trying to work out if the crash is a symptom of the browsers resubmitting the failed requests and we've hit a Solaris bug that we haven't got a patch for, Or if the two errors are unrelated and it was coincidence that we panicked whilst having mod_jk errors. Any help/pointers in resolving the mod_jk error would be appreciated, I included the brief crash information as it may be relevant.
