Things might get gradually slower, if you add a huge number of mounting rules (JkMount or uriworkermap.properties).

mod_jk MAX WORKERS
Hi, we have noticed when we get close to 150 workers/2000bytes defined in our worker.list - mod_jk 1.2.20 starts to break (could not find worker for worker name=xyz) Looking at the code - cause the release notes /changelog don't seem to mention this - looks like 1.2.28 has a new formula for defining JK_SHM_DEF_SIZE - need more digging to get an absolute on this: 1.2.20: ../../tomcat-connectors-1.2.20-src/native/common/jk_shm.h:#define JK_SHM_WORKER_SIZE JK_SHM_ALIGN(sizeof(jk_shm_worker_t)) ../../tomcat-connectors-1.2.20-src/native/common/jk_shm.h:#define JK_SHM_DEF_SIZE (JK_SHM_MAX_WORKERS * JK_SHM_WORKER_SIZE) 1.2.28 ./common/jk_shm.h:#define JK_SHM_MAX_WORKERS64 ./common/jk_shm.h:#define JK_SHM_DEF_SIZE JK_SHM_AJP_SIZE(JK_SHM_MAX_WORKERS) + JK_SHM_LB_SUB_SIZE(JK_SHM_MAX_WORKERS) + JK_SHM_LB_SIZE(JK_SHM_MAX_WORKERS) Anyone know what the limits are on 1.2.28 in terms of workers? thanks! - To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org For additional commands, e-mail: users-h...@tomcat.apache.org
