[jboss-jira] [JBoss JIRA] Commented: (JBAS-4287) run.sh can consume 100% single CPU resources on Solaris

run.sh can consume 100% single CPU resources on Solaris ------------------------------------------------------- Key: JBAS-4287 URL: http://jira.jboss.com/jira/browse/JBAS-4287 Project: JBoss Application Server Issue Type: Bug Security Level: Public(Everyone can see) Components: Other Affects Versions: JBossAS-4.0.5.GA Environment: Solaris on SPARC (version 9 & 10) Reporter: Quenten Alick Assigned To: Dimitris Andreadis Fix For: JBossAS-4.2.0.GA Attachments: run.sh, run.sh.patch When shutting down jboss the run.sh script remain alive and consumes 100% of a single CPUs resources. run.sh needs to be killed off. To trigger the bug, you need to 1) set LAUNCH_JBOSS_IN_BACKGROUND 2) start the jboss server normally 3) Once it's started stop the server At this point the JVM stops, however the run.sh script remains running consuming 100% of a single CPUs resources. The problem seems to be this bit of script, plus the fact that the script shebang is #!/bin/sh while [ "$WAIT_STATUS" -ne 127 ]; do JBOSS_STATUS=$WAIT_STATUS wait $JBOSS_PID 2>/dev/null WAIT_STATUS=$? done On Solaris, /bin/sh is *real* bourne shell and the wait shell-built-in for /bin/sh on Solaris returns 0 (not 127) if the PID (passed as an argument) doesn't exist. The man page for wait states that this is the correct behaviour. Therefore wait returns 0 and the while loop continues forever burning up CPU resources (until you kill it with one of the signals not being trapped). Here's a link to the patch that may have introduced the bug. http://jira.jboss.com/jira/browse/JBAS-3748
