Re: [Wrapper-user] Fatal error in Wrapper

[Heather L. <hea...@th...>]

Leif,

Version: 3.2.0
Platform: Windows Server 2003

I have verified that wrapper.jar, wrapper.exe and wrapper.dll are all
from the same version.

The error occurred at least 11 days after the JVM was launched so
definitely not at start up.  After the crash was discovered, the service
was restarted without error (a couple of days later).  Unfortunately, I
have been unable to reproduce the error.  Since it occurred in
customer's production system, I have copied their installation on my
machine to try to reproduce the error.  In this way, I can reproduce the
exact conditions when the error occurred.  However, it is not exactly
the same system.  Since the application receives data over a socket, is
it possible for the client to send something that would cause this
error? =20

Thanks,
Heather

Heather,
    You somehow figured out a way to crash the Wrapper process itself. =20
Unfortunately,
this is a state that the Wrapper is not able to recover from on its own.
I would definitely like to figure out a way to reproduce this as this is
the first I have heard of this problem.

    Could you tell me what version of the Wrapper you are using as well
as the platform.
Are you sure that you are using the wrapper.jar, wrapper.exe, and
wrapper.dll all from the same version?

    The message about packet type 110 is perplexing.  Packet Id #110 is
the access key.
I double checked the code, but this is only sent from the JVM to the
Wrapper process
and then only once at startup.   Your error log shows that this packet=20
Id 110 was
received by the JVM from the Wrapper.

    How long after the JVM was launched did you encounter this error?

Cheers,
Leif
