[Savannah-hackers-public] vcs0 /var partition was full

[Glenn Morris]

Hi,

I got this message after pushing a commit to the emacs git repo:

    remote: postdrop: warning: uid=66918: No space left on device
    remote: sendmail: fatal: gm(66918): queue file write error

And indeed the vcs0 /var partition was 100% full.
The size of /var was 3.8GB, and almost all of this was /var/cache/cgit.
There were 5 files there bigger than 100MB, so I just deleted them.
Hope this was ok.

Obviously some limit needs to be put on the size of the cgit cache,
or this will happen again. Looks like /etc/cgitrc has cache-size=10000,
but apparently this refers to the number of entries. Does not help if
they are all 500MB... :(
