SID-01469: Problems saving pages

Status:	Answered	TWiki version:	5.1.1	Perl version:	5.12.3
Category:	CategoryEditing	Server OS:	Mac OS X 10.7.4	Last update:	13 years ago

A number of users of my TWiki have reported getting the following error message when trying to save pages:

Safari can't open the page .... because the server unexpectedly dropped the connection. This sometimes occurs when the server is busy. Wait ....

I have determined that the error is not due to server load, but after a lot of debugging found that it is related to headings on the TWiki page. For example, the following page:

---+ Integration Coordination

1 2 3
---++ Operations Meetings
   * next meeting: [[OperationsMeeting120518][May 18]]
   * previous meeting: [[OperationsMeeting120511][May 11]]
   * [[OperationsMeetingArchive][Operations Meeting archive]]

produces the error. When I try to edit this page with the WYSIWYG editor I get the following error:

There was a problem retrieving http://teacher.pas.rochester.edu:8080/wiki/bin/rest/WysiwygPlugin/tml2html: GENERAL 0

When I remove the second heading:

---+ Integration Coordination

1 2 3
 Operations Meetings
   * next meeting: [[OperationsMeeting120518][May 18]]
   * previous meeting: [[OperationsMeeting120511][May 11]]
   * [[OperationsMeetingArchive][Operations Meeting archive]]

the page saves fine and I can use the WYSIWYG editor to make further changes.

I tried to reproduce this in the sandbox on TWiki.org and created

http://twiki.org/cgi-bin/view/Sandbox/FrankWolfsTestTopic

I do not get any problems with editing this page, so it is clear that my setup is at fault. However, I have no clue where to look for a solution. For example, searches for the WYSIWYG error message do not help since the WYSIWYG editor works fine on most pages (and version number problems should generate this problem for all uses for the WYSIWYG editor).

Any ideas are welcome ..... very much needed.

Note: I have experienced this problem in with both version 10.6 and 10.7 of Mac OSX.

Discussion and Answer

That is a tough one to debug.

• Do you run TWiki under a Perl accelerator such as mod_perl? If so disable to see if that makes any difference.
• Try to disable all non-standard plugins to see if there is a plugin interference.
• Examine the Apache error logs.
• Network issue? To test try to access the TWiki server from a network close to the server, such as from the data center.

Here are some answers:

• Mod_perl is disabled.
• I disabled all plugins I installed (BatchUploadPlugin and ImageGalleryPlugin) and this did not make any difference. I am not sure if all plugins that came with the 5.1.1 installation are considered standard plugins.
• The apache error log shows the following error when saving does not work: [Wed May 30 16:29:40 2012] [error] [client 74.44.75.5] (54)Connection reset by peer: Error reading request entity data, referer: http://teacher.pas.rochester.edu:8080/wiki/bin/edit/Sandbox/WarehouseIntegrationCoordinationNew2?t=1338409751;nowysiwyg=1
• It is not a network issue. I get the same error if I run the browser on the same machine as the apache server runs.

Although I have not solved this problem, I have found that I can resolve it if I replace the "---+ " tags with html tags "<h1> ..... </h1>", "---++ " by "<h2> .... </h2>", etc.. I am not sure if this points toward a particular source of the problem.
