How would I check the threads for httpd? It normally hangs on startup so there should be enough system threads. Would a GC be required when the system has just started? I have run my startup scripts years so maybe tomcat 8.5.x needs something extra, memory? (see setenv.sh below) I have reverted back to 8.0.x and it starts and runs OK with no issues. My setup: workers.properties: worker.list=worker1 worker.worker1.type=ajp13 worker.worker1.host=localhost worker.worker1.port=8009 worker.worker1.lbfactor=50 worker.worker1.socket_keepalive=1 tomcat.conf ... JkWorkersFile "/etc/httpd/conf.d/workers.properties" # Set the log file JkLogFile "/etc/httpd/logs/mod_jk.log" JkShmFile "/etc/httpd/logs/jk-runtime-status.log" JkLogLevel info JkLogStampFormat "[%a %b %d %H:%M:%S %Y]" .... <VirtualHost *:80> ... JkMount / worker1 JkMount /* worker1 </VirtualHost> setenv.sh : export CATALINA_OPTS="$CATALINA_OPTS -Xms256m" export CATALINA_OPTS="$CATALINA_OPTS -Xmx768m" export CATALINA_OPTS="$CATALINA_OPTS -Xss256k" export CATALINA_OPTS="$CATALINA_OPTS -XX:+UseParallelGC" export CATALINA_OPTS="$CATALINA_OPTS -XX:MaxGCPauseMillis=1500" export CATALINA_OPTS="$CATALINA_OPTS -XX:GCTimeRatio=9" export CATALINA_OPTS="$CATALINA_OPTS -server" export CATALINA_OPTS="$CATALINA_OPTS -XX:+DisableExplicitGC" Not sure where these exports came from but they seem to work up to 8.5.x Cheers Greg.
