JK 1.2.14.1 SIG BUS Error on Solaris 9
I tried to upgrade our JK modules from 1.2.12 to 1.2.14.1 and now every Apache process crashes while processing a request with: [Fri Sep 02 14:23:54 2005] [notice] child pid 11079 exit signal Bus error (10) For every request in the logs. The config works fine with JK 1.2.12 (I can swap it in and things work) and looks like: == httpd.conf: == JkShmSize 60 JkShmFile logs/jk1.shm JkWorkersFile conf/workers.properties JkMountFile conf/uriworkermap.properties JkLogFile logs/mod_jk_log JkLogLevelinfo JkLogStampFormat [%a %b %d %H:%M:%S %Y] JkRequestLogFormat %w %V:%p%U%q %s %T Location /jkstatus/ JkMount jkstatus Order deny,allow Deny from all Allow from 127. /Location == workers.properties: == ps=/ worker.list=jkstatus,CAMCentral_lb worker.jkstatus.type=status worker.CAMCentral_lb.type=lb worker.CAMCentral_lb.balance_workers=ap1lnx60,ap1lnx61 worker.ap1lnx60.type=ajp13 worker.ap1lnx60.host=3.130.232.239 worker.ap1lnx60.port=15753 worker.ap1lnx61.type=ajp13 worker.ap1lnx61.host=3.130.233.24 worker.ap1lnx61.port=15753 == uriworkermap.properties == /CAMCentral/*=CAMCentral_lb /CAMCentral=CAMCentral_lb Apache version: Server version: Apache/2.0.52 Server built: Oct 28 2004 12:24:42 Server's Module Magic Number: 20020903:9 Architecture: 32-bit Server compiled with -D APACHE_MPM_DIR=server/mpm/worker -D APR_HAS_MMAP -D APR_USE_FCNTL_SERIALIZE -D APR_USE_PTHREAD_SERIALIZE -D SINGLE_LISTEN_UNSERIALIZED_ACCEPT -D APR_HAS_OTHER_CHILD -D AP_HAVE_RELIABLE_PIPED_LOGS -D HTTPD_ROOT=/usr/local/apache2 -D SUEXEC_BIN=/usr/local/apache2/bin/suexec -D DEFAULT_SCOREBOARD=logs/apache_runtime_status -D DEFAULT_ERRORLOG=logs/error_log -D AP_TYPES_CONFIG_FILE=conf/mime.types -D SERVER_CONFIG_FILE=conf/httpd.conf What am I missing?
