Summary: Unstable builds due to "SEVERE: I/O error in channel
Channel to Maven"
Key: JENKINS-13171
URL: https://issues.jenkins-ci.org/browse/JENKINS-13171
Project: Jenkins
Issue Type: Bug
Components: core
Affects Versions: current
Environment: Linux Ubuntu, Tomcat 6.x
Reporter: Miguel Almeida
I am submitting this as per Richard Mortimer's suggestion in
https://issues.jenkins-ci.org/browse/JENKINS-12037?focusedCommentId=160224&page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#comment-160224
I've just posted on the mailing list
(http://groups.google.com/group/jenkinsci-users/browse_frm/thread/7f96cdf57ffed6cf#
) - perhaps this is the same issue.
I have a multi-module project where I'm running the Maven goal "clean
surefire-report:report".
While the tests pass in our local machines, we're randomly having failures
in one of the modules in Jenkins. The console shows:
{noformat}
mavenExecutionResult exceptions not empty
message : Failed to execute goal
org.apache.maven.plugins:maven-surefire-plugin:2.12:test
(default-test) on project cm-web: Error occurred in starting fork,
check output in log
cause : Error occurred in starting fork, check output in log
Stack trace :
org.apache.maven.lifecycle.LifecycleExecutionException: Failed to
execute goal org.apache.maven.plugins:maven-surefire-plugin:2.12:test
(default-test) on project cm-web: Error occurred in starting fork,
check output in log
{noformat}
We have Jenkins running in Tomcat and by running the build and inspecting
tomcat's log I see:
{noformat}

Restarting tomcat makes the problem go away (until it "randomly" appears again
after a few days)
