Re: [Wrapper-user] RE: JVM exit - no log error entries

[Paul C. <cas...@au...>]

Leif,

The Wrapper (as always!) was behaving as it should.  Strange thing is -
while reproducing exactly the same crash (ie, I've documented the exact
steps to reproduce it), the JVM was inconsistent in generating a hotspot
error log - and hence hotspot error output in the Wrapper log file.  Any
timeout values I can tweak to make this more consistent?

I'll have to search the bug database to see if this is a new bug.  I've
found some similar, but I need to investigate more thoroughly - when I have
time.

Regards,

Paul Casanova

Paul,
    Kudos tracking that down.  I can imagine it was not fun.  Is it a
known Sun bug or
did you find something new?

    I wanted to confirm that you now believe that things are working
correctly as far as
the Wrapper is concerned.  The JVM was crashing due to this bug and the
Wrapper
was restarting it.

Cheers,
Leif
