Ben,
This is not a failure mode that I have seen before. At the point you are
getting the error message, the Wrapper has succeeded in launching the JVM,
the WrapperManager class in the JVM has initialized and opened a connection
back to the Wrapper process, sending its access key. The Wrapper then
responds by sending a START packed to the, JVM telling it it is time to
start
its application.
The sending of this START packet is failing for some reason. This would be
the first packet that the Wrapper attempts to send to JVM. Reviewing the
source, there is only 1 possible error at this point in the lifecycle.
That is a
failure at the socket level sending the packet. If you could reproduce this
with the wrapper.debug=true property set, I would be able to tell what the
exact failure is.
What does your system look like when this starts happening? Are you
under high load, low on resources or memory? This could happen if the
JVM process was crashing at exactly that moment. I am only guessing at
this point and will need more information.
Cheers,
Leif
