Thread issue - org.apache.tomcat.util.threads.ThreadPool logFull
Does anyone know what would cause the following error
Nov 4, 2009 9:30:28 AM org.apache.tomcat.util.threads.ThreadPool logFull
SEVERE: All threads (150) are currently busy, waiting. Increase
maxThreads (150) or check the servlet status
I'm fronting apache tomcat 5.5.26 with apache 2.2.8 and mod_jk
My workers.properties file looks like
--------------------------------------------------
worker.list=ajp13,status
worker.status.type=status
worker.ajp13.type=ajp13
worker.ajp13.host=localhost
worker.ajp13.port=8009
worker.ajp13.socket_keepalive=1
worker.ajp13.connection_pool_timeout=600
worker.ajp13.connect_timeout=10000
worker.ajp13.prepost_timeout=10000
--------------------------------------------------
My AJP connector looks like
<Connector port="8009"
maxThreads="150" minSpareThreads="25" maxSpareThreads="75"
connectionTimeout="600000" maxKeepAliveRequests="1"
enableLookups="false" redirectPort="8443" protocol="AJP/1.3" />
Is the 150 the error message refers to the maxThreads on my AJP
connector? Should this be increased?
Would enabling a log4j email appender cause this? I set one up today
but haven't gotten any email though.

Likely that the threads are off stuck somewhere they shouldn't be. Take a thread dump and find out what's going on. No point in speculating when real data is easily available.
