Question

• TWiki version: TWikiBetaRelease 30 Dec 2002
• Perl version: 5.8.0
• Web server & version: Apache/2.0.40 (Red Hat Linux)
• Server OS: RedHat Linux 8.0
• Web browser & version: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.0.2) Gecko/20021120 Netscape/7.01
• Client OS: RedHat Linux 8.0

When I save a file in the twiki web it takes more than 5 minutes to save. The first time it happened I was saving TWikiPreferences and the second time it was InterWikis. My machine is not that slow. I'm running the latest beta. To install it I unzipped it in the older releases (Athens) twiki folder. Maybe that is the problem. There is nothing in the error_log for apache. Are there any other twiki related log files to look through? The testenv script only reports these warnings:

• Warning: Unable to set locale to en_US.ISO-8859-1, actual locale is C - please test your locale settings.
• Warning: Since your CGI script is not running as user nobody, you need to change the locks in the *,v RCS files of the TWiki distribution from nobody to apache. Otherwise, changes to topics will not be logged by RCS.

I have changed the *,v files to be locked by apache. Is there anything else I should look at to troubleshoot this problem?

Answer

This may be related to Perl 5.8 / Apache 2.0. TWiki isn't tested all that well with either of those. However, I don't really have any productive suggestions on how to go about fixing the problem, or even tracking down where the problem is occurring.

Maybe it is a perl 5.8 / apache 2.0. I am running apache 2.0.43 / perl 5.6.1 on another machine and it never has this problem.

Some TWikiDebugging is required here - note that Perl 5.8.0 is not recommended currently, because it is rarely tested and has some unusual issues. I don't think the locale messages are significant here, although they do indicate a problem with your locale setup.

There are some topics about this, try Google:perl+5.8+twiki and UsingPerl58OnRedHat8 - lots of people have had problems with RH 8.0 (see also TWikiOnRedHat).

The long delay means that perhaps there is some network activity going on - have a look with tcpdump or Ethereal perhaps to see if there are DNS lookups or whatever?

I would definitely recommend a clean install of the beta initially - then you can try an overwrite-the-old install, or preferably just copying over some topics.

I recently copied my twiki from a Redhat 7.3 using perl 5.6 over to a SuSE 8.1 with perl 5.8. I had this problem after after I got everything setup. It literaly took 5 minutes to bring up the preview and another 5 minutes to save the changes.

It turned out that my problem was a user rights issue. My data directory had a mixture of owners. Some files were owned by the user that the web server ran as (nobody) and other files were set as root.

Once I chown'd all of the files to nobody:nobody then the problem cleared up immediatly.

I am having a simmilar problem with the newest twiki and perl 5.8.4.. Every time I log into my twiki it takes ages when I want to upload a file or save changes of a site for the first time. The strange thing is that once the first upload/update is completed (which takes quite a while - probably something around 5 Minutes), all following uploads or updates work just fine and without delays. Is there any way I can fix this issue without falling back onto an older version of apache and/or perl?
