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

[Dan Berindei (JIRA)]

    [ https://issues.jboss.org/browse/ISPN-1890?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12675302#comment-12675302 ] 

Dan Berindei commented on ISPN-1890:
------------------------------------

Sanne, I should have mentioned that it's the same thing. But I talked to Scott and he actually didn't have it set, so I guess it's always good to check with ulimit rather than trust that the limits.conf settings have been applied correctly.

I just wanted to make it clear, in case someone else gets here wondering about this error, that it's usually about the number of processes (on Linux) or the native memory (on 32-bit Windows, since threads will have a bigger stack by default) - and never about the heap settings.
