Re: unable to get address of epoll functions, pre-2.6 kernel

[Emmanuel Lecharny]

Seems to be a problem with Java 6 in combinaison with GRSecutity.
Use the - 
Djava.nio.channels.spi.SelectorProvider=sun.nio.ch.PollSelectorProvider 
flag. I don't see any other solution...

Hi Emmanuel, 

Good suggestion.  Unfortunately I get the same error - the stack trace line number did change though so it would seem that I am using the new java version - that's what the ps -ef and the which java are supposed to show below..  

Any other ideas?

Oh I am using tomcat 6.0.16 if that matters.

Hi,

seems to be a pretty common error on Lunux with Java 6...

Have you tried with an more recent version of JDK? Sun
JDK's current 
version is 1.6.0_06-b02, when JDK 1.6.0-b105 was the very
first version 
of Java 6.

Anyone get this error before?  It prevents apache-ds
      
from loading as the web application.
    
I see this in:

# uname -r
2.6.23.14-grsec

I have found that to fix it I can append:


      
-Djava.nio.channels.spi.SelectorProvider=sun.nio.ch.PollSelectorProvider
    
but I'd prefer not to have to do this.  

This is on java:

$ java -version
java version "1.6.0"
Java(TM) SE Runtime Environment (build 1.6.0-b105)
Java HotSpot(TM) Client VM (build 1.6.0-b105, mixed
