[infinispan-issues] [JBoss JIRA] (ISPN-1890) Unable to create new native thread when running core/ testsuite

[Scott Marlow (JIRA)]

    [ https://issues.jboss.org/browse/ISPN-1890?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12674826#comment-12674826 ] 

Scott Marlow commented on ISPN-1890:
------------------------------------

Does anyone have a workaround?  This happens everytime that I try to build on Linux with Oracle jdk 1.6.0_26 or 1.6.0_31.  Also tried "MAVEN_OPTS=-Xmx1024m -Xms512m -XX:MaxPermSize=128m"

It sounds like a leak to me but I'm not sure why I'm the only one hitting this (Galder only experienced this once and it went away).
