Error flushing message buffer to client

Postby jimc » Fri Jun 17, 2005 2:24 am

Servoy version R2 2.2-build 328, repository version 25
os.name=Windows 2000

For one person on the LAN, when they try and Print a page the client abruptly shuts down and the server log gives the following message:

2005-06-16 08:43 : Error flushing message buffer to client a49d96e6-de63-11d9-8cec-f0047e5f1602, Connection refused to host: 192.168.202.138; nested exception is: java.net.ConnectException: Connection refused: connect

Curiously, after all have logged off the solution and gone home, I will go into servoy-admin and under the client page there will be three of this person listed!

This person can log in on another machine and print without problem.

Could someone give me a potential starting point for troubleshooting this?

Re: Error flushing message buffer to client

This looks like a completely different problem.
The first looks like a native code incompatibility (or bug of some sort) in the printing subsystem between Win 2000 and some native java code. (that happened many years ago)

What you see looks just like a data type mismatch in the solution. It was better if you created a separate topic instead of reviving this very old one.

1. What Servoy version do you use, what OS and java versions do you use?
2. What exactly does the user do when that error message pops up?
3. Is it related to find mode? Is find used in that area of code?

It may simply be that somewhere in JS code you try to set a string value into a "Date" dataprovider without being in find mode...
