--------------------------------------------
Summary: Windows 7 sessions disconnect when certain events take
place
Key: GUACAMOLE-1363
URL: https://issues.apache.org/jira/browse/GUACAMOLE-1363
Project: Guacamole
Issue Type: Bug
Affects Versions: 1.3.0
Reporter: Dominik Borkowski
Attachments: guacd_1.3_errors_with_windows_7.txt
Hello,
When upgrading from guacamole 1.2.0 to 1.3.0 we noticed a problem with our
Windows 7 images: they are disconnected, then they reconnect a few seconds
later.
This behavior is 100% repeatable for us, and happens when:
* user logs in, and clicks on 'activate now' or 'activate later' pop-up menu
* user clicks on the start menu
* user clicks on the clock on the task bar
* user clicks on the internet explorer icon on the task menu
Enabling debug levels on guacd shows that each disconnect with the
`Stream_GetRemainingLength` message, eg:
```
guacd[30]: DEBUG: Stream_GetRemainingLength(s) 1509 < 3342
guacd[30]: DEBUG: order flags ff failed

guacd[30]: DEBUG: Client terminated successfully.

guacd[6]: INFO: Creating new client for protocol "rdp"
guacd[6]: INFO: Connection ID is "$8a4db747-cb8a-4675-aeab-2ea194a971f4"
```
We can always reproduce this issue, but the problem goes away if we deploy
guacamole 1.2.0. Each deployment is clean, so there's no upgrade in place. Our
windows 7 instances are AMIs, and we can repeat this on every new instance.
Any help would be greatly appreciated.
Cheers!
