Several times today, users have not been able to access solutions on the Servoy server from both the local network and over the internet. The status bar goes through the whole procedure and stops at 'Ready', but never shows the solution. The client must then be force quit. In the server log, I see these errors:

Code: Select all: 2006-12-12 16:47 TaskExecuter[1] ERROR com.servoy.j2db.dataprocessing.ClientManager java.rmi.ConnectIOException: Exception creating connection to: XXX.XXX.XXX.XXX; nested exception is: java.io.InterruptedIOException: The socket pool for a client XXX.XXX.XXX.XXX:XXXX did not recieve a callback socket from the client within 60000ms, pool still empty 2006-12-12 16:47 TaskExecuter[1] ERROR com.servoy.j2db.dataprocessing.ClientManager Error flushing message buffer to client 20b7e555-8af1-4e4f-97b3-42eca2203f1c, Exception creating connection to: XXX.XXX.XXX.XXX; nested exception is: java.io.InterruptedIOException: The socket pool for a client XXX.XXX.XXX.XXX:XXXX did not recieve a callback socket from the client within 60000ms, pool still empty 2006-12-12 16:46 RMI TCP Accept-1099 ERROR com.servoy.j2db.util.Debug ServerTwoWaySocket accept failure java.net.SocketException: socket closed at java.net.SocketInputStream.socketRead0(Native Method) at java.net.SocketInputStream.read(Unknown Source) at com.sun.net.ssl.internal.ssl.InputRecord.a(Unknown Source) at com.sun.net.ssl.internal.ssl.InputRecord.read(Unknown Source) at com.sun.net.ssl.internal.ssl.SSLSocketImpl.a(Unknown Source) at com.sun.net.ssl.internal.ssl.SSLSocketImpl.j(Unknown Source) at com.sun.net.ssl.internal.ssl.SSLSocketImpl.a(Unknown Source) at com.sun.net.ssl.internal.ssl.AppInputStream.read(Unknown Source) at java.io.BufferedInputStream.fill(Unknown Source) at java.io.BufferedInputStream.read(Unknown Source) at java.io.DataInputStream.readInt(Unknown Source) at com.servoy.j2db.util.a.d$b.accept(Unknown Source) at sun.rmi.transport.tcp.TCPTransport.run(Unknown Source) at java.lang.Thread.run(Unknown Source)

Attatched is the entire server log from 2:00pm to 4:45pm. Could someone who understands what this says give me some insight as to what might be happening? Restarting the Servoy service fixes the problem for now, but it does not stay fixed.

I don't know but: have you changed (to a or) your SSL connection? It looks like there is an issue with you connection.

According to the people who manage the server machine and the network itself, there had been no changes. I thought it might have been a sketchy internet connection, but the problems occurred on the local network as well.

sent to me, by Steve In LA ... Posted for info only:

In order to fix this, you MAY have to do one or all of the following on the client machine:

1) Delete the .servoy folder found in the Documents and Settings>*username* folder. On the PC, you may have to show hidden files and folders to see this. On the Mac, this folder is found in the Users>*username* folder.
2) Delete and remake and desktop icons that clients may use to conect to your solution. Occasionally, bad settings will be kept after a new version of the solution is loaded or an update to Servoy is done.
3) Using the Java control panel, delete any temporary Java files.
4) Delete andy temporary files for the client's Internet browser.

Hopefully this will help you.

I'm having the same issue, however, people are working in the solutions... having connected to it for hours... and suddenly it stops working so I don't think it's an ssl issue:

2008-10-16 16:02:24 : Loading servoy.properties from C:\Program Files\Servoy\servoy.properties

Any clues?

Still getting these errors, still restarting the production server when things slow down, but now I've got some new and wonderous (wonderful/curious) errors:

They seem to be happening on two different Citrix Servers: 10.1.1.12 and 10.1.1.19... The latter is virtual and sits on top of the first, which is physical. However, there is another virtual/physical server relationship just like this one where I don't seem to be getting these errors, at least this time around.
