Hi,
for those who can't wait for the next release of R6 (6.04 and 6.51) here is how to make Domino work on Redhat Enterprise versions.
Problem ist JRE which crashes when started under RH ES 3.
To get it running do a manual server setup,
download JRE 1.3.1 from here
http://www-106.ibm.com/developerworks/java/jdk/linux140/,
install it and exchange the domino jre wit the new one.
Just do some symbolic links and it works.
This clearly unsupported but everything runs fine here.
