[jira] [Commented] (GUACAMOLE-521) PDF generated by Guacamole
printer ends up corrupted if document is at least 18 pages long
[ https://issues.apache.org/jira/browse/GUACAMOLE-521?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16389916#comment-16389916 ]
Nick Couchman commented on GUACAMOLE-521:
-----------------------------------------
Pretty sure it has nothing to do with page count. I printed the SSH RFC (https://tools.ietf.org/html/rfc4253), which is 33 pages, and it printed fine, twice in a row. I copied the URL you mentioned (Java Index page) and printed it, and got all 82 pages just fine.
My initial suspicion, based on you're statement that you're running in a docker container, is that something is running out of RAM or disk space to process the file. It doesn't look like it uses all that much, but it may use just enough to put it over the edge. Other than that, if you're running a proxy in front of the Guacamole Client it's possible it's closing the connection.
I'm running Guacamole on CentOS7, so same ghostscript packages you're using, but I'm not running in Docker, and I'm running the latest version out of the git tree. I don't think there have been any big changes for printing since 0.9.14 was released, though, so I suspect it's some other issue inside Docker and not something specific to Guacamole.

> Key: GUACAMOLE-521
> URL: https://issues.apache.org/jira/browse/GUACAMOLE-521
> Project: Guacamole
> Issue Type: Bug
> Components: guacd-docker
> Affects Versions: 0.9.14
> Environment: Running the official Docker containers from guacamole/guacamole:0.9.14 and guacamole/guacd:0.9.14
> Reporter: Renan Melhado
> Priority: Major
> Attachments: resize-guacamole-after-corrupted-pdf.png
>
>
> When printing any document with at least 18 pages to the Guacamole printer, the resulting PDF ends up corrupted (Ghostscript crashes), and the RDP session is disconnected in the next window resize event.
> # Open a document with at least 18 pages, i.e. [https://docs.oracle.com/javase/7/docs/api/index-files/index-1.html]
> # Print the whole document with the Guacamole printer and try to open the resulting PDF file. It'll be corrupt.
> # Go back to the Guacamole RDP tab on the browser and resize the window to trigger the reconnect. The RDP session will be disconnected.
