[Jean-Frederic Clere (JIRA)]

    [ https://jira.jboss.org/jira/browse/MODCLUSTER-120?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12514938#action_12514938 ] 

Jean-Frederic Clere commented on MODCLUSTER-120:
------------------------------------------------

ipcs -m | awk ' { print $2 } ' | xargs -n 1 ipcrm -m
Could be use to remove shared memory left by httpd once kill with -9 (or crashed).
