NioEndpoint.getPoller0 throws NPE
Hello everybody,
I'm running tomcat 6.0.14 on Linux. It worked fine for a couple of days
then, after a reboot, the NIO connector failed throwing the following
exception
03-Feb-2008 14:37:05 org.apache.tomcat.util.net.NioEndpoint
setSocketOptions
SEVERE:
java.lang.NullPointerException
at
org.apache.tomcat.util.net.NioEndpoint.getPoller0(NioEndpoint.java:484)
at
org.apache.tomcat.util.net.NioEndpoint.setSocketOptions(NioEndpoint.java:985)
at org.apache.tomcat.util.net.NioEndpoint
$Acceptor.run(NioEndpoint.java:1169)
at java.lang.Thread.run(Thread.java:619)
The NIO connector is configured as follows in server.xml
<Connector port="8081"
protocol="org.apache.coyote.http11.Http11NioProtocol"
redirectPort="8443" connectionLinger="20"
connectionTimeout="10000"
keepAliveTimeout="5000" maxKeepAliveRequests="20"
socket.tcpNoDelay="true"
socket.soKeepAlive="true" socket.soReuseAddress="true"
socket.soLingerOn="true" socket.soLingerTime="5"
acceptCount="10" acceptorThreadCount="2"
useComet="false" maxThreads="100" minSpareThreads="5"/>
I've a cluster of machines running tomcat 5.5 + Axis2 which send a
message to tomcat 6 instance when they start up, when the error
happened.
On the other side the error was the following:
