Question

Me and my collegues at work have the problem that twiki hangs on the very first 'save' in twiki for about 5 Minutes.

It makes no difference if the page to be saved is newly created or if it is an already existing page.

After this very first save the 'hang' does not occur anymore (until you again close and startup the browser).

This issue seems to be browser and OS independent. We use Mozilla, Firefox, IE and Apple Browers.

I have not found this topic adressed somewhere. Maybe someone can give me a hint what is going on?

The installed skin is 'Koala'

Answer

The first save after server restart? Or the first save in a new browser? If the former, check your logs for problems on the server. if the latter, you are probably having connection problems to your webserver; again, check the logs.

It happens reproducable in the first save in a new Browser.

You wrote that I'm having connection problems. But than I would expect that

• the problem is not always reproducable
• similar problems occur from time to time after the first save, - but it doesn't.

Seriously, this is more likely to be an Apache issue than anything to do with TWiki. Check your server logs, especially error_log.

I have seen problems like this before, and they have always been something to do with the webserver, usually authentication.

It might also be related to network problems. I.e. it could be related to DNS-lookups or cache/proxy-implementations (bad configuration of a MS IAS-server or similar).

I would try using a simple browser from the server itself (i.e. lynx) first - to be certain any network connectivity problems are eliminated.

After that, you could verify that the problem exist and is "cross-browser" (i.e. reproducable on both firefox, internet explorer and opera), and both having and not having the network proxy in the loop.

We see the same problem on our TWiki install. Happens across machines (Linux, OSX, Windows) and browsers (Firefox, Safari, IE, lynx). I tried Steffen's suggestion of running lynx on the actual server, but I get the same result.

The httpd logs don't seem to help. No errors and nothing shows up in the access logs until the page actual loads up in the browser. It's as if the page load request goes to never-never-land for a while. But, I don't know what triggers it to work--is it a re-request from the browser, or the httpd server finding the original request. ???

You don't state the version of apache you are running, but presumably it's a version 2?

Google:twiki+apache+two+timeout gives you various issues that share some of their nature with your problem - and some suggestions for workarounds etc as well.

If you have no special reasons for running an Apache v2.0, I'd suggest a switch to v1.3. - At least that might be the most simple way to eliminate the problem.

-- SteffenPoulsen - 27 Apr 2005

Sorry.. Apache 2.0.50. I already tried the Apache 2.0 workaround and that didn't help. And, I'm not the admin person, so I don't get to roll Apache back to 1.3.

On the other hand, I checked out the link you gave above, used the fix for bin/oops and all is happy now! We'll see how things work in the long-term, but in my quick tests, it seems to work just fine.

Thanks!
