cgit v0.10.2-26 + apache2 = random 500 Internal Server Error

[fabien.bagard]

Hi list !

I do face a strange problem with cgit 0.10.2-26 (Pulled from git).

All my repos are correctly scanned, but after a random amount of time, from 5 secondes to tens of minutes, it seems something stops working : Apache2 throws ans error 500 : Internal server error.
Sometimes it starts to work again, but most of the time, I have to reload apache. Not using apache is not a solution



Here are revelant informations :

Permissions are correct on scan-path.

cgitrc:
cache-root=/var/cache/cgit/
cache-size=500
section-from-path=1
snapshots=tar.gz tar.bz2 zip
clone-prefix=ssh://login at git.company.org
#extra display
enable-commit-graph=1
max-stats=year
#scan
scan-hidden-path=0
scan-path=/data
max-repo-count=5000
# coloration syntaxique
source-filter=/usr/local/lib/cgit/filters/syntax-highlighting.sh

apache2 vhost:
[...]
  RewriteEngine   on
  # Don't modify the urls to *.png and *.css files
  RewriteRule ^/(.*\.png)$ /$1 [L]
  RewriteRule ^/(.*\.css)$ /$1 [L]
  # remove cgit.cgi from the url
  RewriteRule ^/(.*)$ /cgit.cgi/$1 [L]

  DocumentRoot /var/www/cgit/
  <Directory "/">
    AllowOverride None
    Options +ExecCGI
    AddHandler cgi-script .cgi
    DirectoryIndex cgit.cgi
    [...]
  </Directory>

content of /var/www/cgit : (Not the best perms, I agree)
$ ls -l /var/www/cgit/
total 5044
-rwxr-xr-x 1 root root 5129317 Jan  2 11:47 cgit.cgi
-rw-r--r-- 1 root root   12520 Jan  2 11:47 cgit.css
-rw-r--r-- 1 root root    1488 Jan  2 11:47 cgit.png
-rw-r--r-- 1 root root     590 Jan  9 11:30 cgitrc

-rw-r--r-- 1 root root      47 Jan  2 11:47 robots.txt


The only log I have from apache is :
Here it works,
[09/Jan/2015:11:31:36 +0100] "GET / HTTP/1.1" 200 55103 "-" "Mozilla/5.0 (X11; Linux x86_64; rv:31.0) Gecko/20100101 Firefox/31.0 Iceweasel/31.3.0"

then, no more

This sounds like an Apache problem and not anything to do with CGit
(although I guess CGit could be triggering the issue).

Since CGit is a CGI process, there is nothing that persists between
requests, so I would not expect a CGit problem to relate to the lifetime
of the Apache process.

Our other vhosts are working as expected. Server is not over-loaded. I guess CGit is triggering the issue, this is why I posted here.
