Strange trac behavior...

For about a week or so have occasionally gotten a weird error when loading an orxonox-trac-page. Instead of the desired page I got an error message like the following:

[Link removed]

After a 1 or 2 reloads, the page showed up properly. Am I the only one, who gets this weird error?

I had this problem too. I think this was due to wrong permission settings in the trac plugin directory.

I think Nicolasc fixed it

He did, a bit. Before it was impossible to even load it after several reloads. It was really based on luck to see anything else than the error page.
But yeah. It is still an often occurrence.
Nicolasc said, that there is something with the log files of the apache server, but it's better he explains it.. and fixes it for real.

If you had asked me last weekend, I would have confirmed the error - but every since, it did not reappear.

What cause the original error - not absolutely sure, but my best guess:
The weekend before, I installed logrotate in order to reduce disk usage - 2GB of apache logfiles ist just to much. Installation was seamless, the test run was successful - but for some reason it did not restart the apache server as requested. One week later - as the logs get rotated on a weekly basis - the script gets run again and restarts apache after having done so. By doing this it may have caused a module which worked fine before to fail...
I am not quite sure what I did to fix it - changing permissions, multiple apache restarts, some other things - and it started to work again. With some trouble in the beginning, but I haven't seen the error since then.

I continue to look into it, but I don't have much time right now - maybe coming weekend or after the exams...

Looking through the servers specs and the entire setup, I found some issues - not sure if I should worry, or just be glad that it works - and that the hardware is coming to its limits - rather full disk and ram...
I mentioned it to beni already - I do have a "old" mainboard with p4, maybe some ram - needs testing - lying around at home which I could donate. (AFAIK we still need to change that housing, don't we?). And I would feel a bit more comfortable having a raid1 setup in that server - so in case of a hdd failure, we can still work on. I don't know about any backups having been run. Feel free to bug me in irc about it....

cheers

The trac problem reappeared today. It happens every first time I request the Orxonox trac page.

Strangely enough the error did not reappear on my system - and I access the trac daily.

What page are you trying to load? Is it a specific one, or does it appear at random. (I normally access the trac through [https://www.]orxonox.net/timeline)

PS: There are some updates lined up for after my exams, but except for apache - which could get messy - nothing that trac directly depends on.
@patrick: Some explanations about the setup might be nice, before I blow it to hell...

cheers

Haven't seen the problem anymore lately. I dunno how to reproduce it at all. Neither new pages, nor pages often or seldom accessed share that behavior. Just occurs sometimes, but as I said. Not that much anymore lately...

I haven't done anything so far...
Did it reappear?

I've seen it a lot during the last days, especially while opening old change sets.

Post by **patrick** » Thu Feb 07, 2008 2:10 pm

I didn't see it lately. But it's still strange... Is there something that changes the permission settings of these directories to prevent them from being read from?

Are you talking about this error: "The following error occurred while trying to extract file(s) to the Python egg cache"?

Today I tired to edit the Debian HowTo... but it hardly showed up. About 4 reloads are needed to see it and none of my edits worked. :-/

This is becoming a serious problem. Not only does it make difficult for us to change the site and navigate, but more importantly:
Since this error occurs more often nowadays, visitors will click away and experience strange errors which they don't understand. Imagine how you would react when that stuff happens on a site you don't know!

This error first occurred when Nico changed and upgraded the wiki. I don't understand the error message. Is there anyone who knows more about python and the trac-wiki?

atm I have 100% chance to get this error. Everybody will think this page is down and the project dead...

Post by **patrick** » Fri Jun 06, 2008 10:59 am

Ok. I have made a hot-fix. It should work now.

If the error reoccurs let me know.

Cool, thanks
