Hello Glenn,

Many thanks for the quick action!
I'm very glad you still have savannah admin access :)

Sadly the entire disk on the new vcs0 VM is 9.8GB,
so this was significant.
Thanks for deleting the large files.

For now, I've reduced the number to 5000,
and also added TTL on static pages cache to 5 minutes (the default
was "never expire") and I suspect few of the large cache files were
for what cgit calls "static" (=pages with fixed SHA1 in the URL).

The new current settings in /etc/cgitrc are:

We might want to consider adding a cron job to delete old/large files ?
something like:
  find /var/cache/cgit -type f -ctime +7 -size +2M -delete

In the long run (as Bob wrote before), it would be better to have bigger
disks, and perhaps put /var/ on a separate partition... one day...

Thanks again,
