My situation is: I Have many applications running in cluster Jboss in the version 4.0.2 and sametimes my two nodes the cluster occurred the following error: ERROR [org.apache.tomcat.util.threads.ThreadPool] All threads (400) are currently busy, waiting. Increase maxThreads (400) or check the servlet status. I already analised the threaddump and I didn´t any things about "memory leak, deadlock and etc.." When this is ocurs my portal becomes unavailable. My configuration is: *) 02 servers running linux version kernel 2.6 *) Version JBOSS is 4.0.2 *) Apache 1.3.37 + Mod_jk.1.2.25 workes.properties # # Servidor Jboss Producao 01 # worker.dcpr0039.port=8009 worker.dcpr0039.host=192.168.0.5 worker.dcpr0039.type=ajp13 worker.dcpr0039.connection_pool_timeout=600 worker.dcpr0039.connection_pool_minsize=10 worker.dcpr0039.connect_timeout=60000 # (1 minute) worker.dcpr0039.prepost_timeout=60000 # (1 minute) worker.dcpr0039.lbfactor=1 # # Servidor Jboss Producao 02 # worker.dcpr0040.port=8009 worker.dcpr0040.host=192.168.0.6 worker.dcpr0040.type=ajp13 worker.dcpr0040.connection_pool_timeout=600 worker.dcpr0040.connection_pool_minsize=10 worker.dcpr0040.connect_timeout=60000 # (1 minute) worker.dcpr0040.prepost_timeout=60000 # (1 minute) worker.dcpr0040.lbfactor=1 server.xml (tomcat) <!-- A AJP 1.3 Connector on port 8009 --> <Connector port="8009" address="${jboss.bind.address}" maxThreads="400" minSpareThreads="150" maxSpareThreads="175" acceptCount="100" emptySessionPath="true" enableLookups="false" redirectPort="8443" protocol="AJP/1.3"/> httpd.conf MinSpareServers 5 MaxSpareServers 20 # # Number of servers to start initially --- should be a reasonable ballpark # figure. # StartServers 10 # # Limit on total number of servers running, i.e., limit on the number # of clients who can simultaneously connect --- if this limit is ever # reached, clients will be LOCKED OUT, so it should NOT BE SET TOO LOW. # It is intended mainly as a brake to keep a runaway server from taking # the system with it as it spirals down... # MaxClients 500 Please, Someone could help me?
