In the debian package version 1.4.4.4, git-daemon's memory by default is
limited to 64MB.  I changed that with 1.5.0, but maybe you chose to not
accept the changes to the run script when upgrading to 1.5.5.1-1.

Check /var/service/git-daemon/run, if it has 'exec chpst -m64000000
git-daemon ...'.  If so, remove 'chpst -m64000000', and restart the
git-daemon service through 'sv restart git-daemon'.

It appears that after upgrading the git-daemon-run from 1.4.4 to 1.5.1,
I didn't do a "sv restart git-daemon".

Probably the package upgrade should have done this for you, my fault.

After running the command I can now do a checkout form the web
repository, yay!

It appears to use 128m of virtual memory when checking out the
repository (which is why it would be hitting the 64Mb limit).

Would adding a "chpst -m256000000" be a good idea?

I personally think so, yes, limiting the memory for long running
processes (services) generally is a good idea.  But finding a good
default for git-daemon isn't easy, as it depends on the repositories it
serves, and requires lots of memory per se.  So on Debian, it's now
unlimited by default.
