Re: [Wrapper-user] FW: CTRL-BREAK/PAUSE trapped

[Scott M. <sco...@di...>]

I apologize for posting the question before getting a complete report from
the customer. They are in Switzerland so it is difficult to gather complete
information. I was working off of a report that was translated from German
to English and it was a bit misleading.

It turns out that the customer was running my app (in Windows) in the
Windows session (rather than as a Windows Service) and thought it was "hung"
so he hit CTRL-BREAK repeatedly to try to shut it down. That is what was
causing the CTRL-BREAK/PAUSE signals. The documentation tells them to enter
a quit command but they didn't read it.

Thanks for your quick response.

Scott

Scott,
Are you referring to the "CTRL-BREAK/PAUSE trapped" message?
It looks like you are running on a Windows machine.

Java has a built in feature to allow the user to request a thread dump
by pressing
CTRL + <the BREAK key>.   The Wrapper also traps this key sequence so it can
be forwarded on to the Java process.

Are you saying that the user is seeing this over and over in the logs?
 I have never
heard of this signal being sourced by anything other than a user key press.
You
can confirm that your customer is not pressing these keys?   If not
then there must
be something else running on the system that is generating those key
press events.

Cheers,
Leif
