[NOTABUG] Re: [Xen-users] Sun and BEA 1.5 64-bit JVMs not happy w/ Xen o

Please can you give us a recipe for provoking the bug using the sun jvm

Running "java -version" causes the issue every time, starting
immediately after boot.
I just strace'd the Sun JVM, and it appears that the only mmap failing
is requesting a full 1GB of RAM, and that only inconsequential amounts
have been allocated hitherto. Looking into this further, I've found
evidence that there's a bug in Sun's 64-bit JVMs causing them to
allocate much more memory than is needed:
http://forum.java.sun.com/thread.jspa?threadID=651637
...and, further, that "ulimit -v" isn't being set appropriately on this
system on account of an administration bug. [Swap was enabled only
*after* boot, whereas SLES calculates the default ulimit -v as a
percentage of total ram+swap at boot time].
Oops; sorry for the noise.
