We are running hudson1.0.3 and using maven build on slave machine.
maven project has a lot of subprojects and build is very slow.
If we check build log it says:
$ /usr/jdk/instances/jdk1.5.0/jre/bin/java -cp
/certipost/data/hudson/maven-agent.jar:/usr/local/maven/core/boot/classworlds-1.1.jar
hudson.maven.agent.Main /usr/local/maven /export/home/certione/slave.jar
/certipost/data/hudson/maven-interceptor.jar

channel started

It is only for maven projects.
We have ant builds on slave also and there there is no timeout

After that it doesn't do anything about 3 minutes and only after that it
launches maven build

Is it some timeout in slave ?
