The filesystem can end up in a state were the filesystem is full and the
returned ss_nongc_ctime is smaller than sui_lastmod of all reclaimable
segments. The garbage collector will not clean anything and therefore no new
room for new files will be available and ss_nongc_ctime/sui_lastmod will not be
updated without using special tools. This makes the filesystem unusable without
manual recovery.

This problem appeared on a current 3.2 stable kernel (Debian Wheezy build). I
am not an FS developer and have therefore not much background knowledge about
the NILFS codebase. Nevertheless, this problem hit me quite hard after creating
some files on a nilfs partition until it was full and deleting them again.
$ for i in `seq 0 150`; do dd if=/dev/zero of=foo$i count=22528; done
$ rm foo*
Looking at the output debugging output using
$ watch -n .5 'df -h;tail /var/log/syslog;'
clearly showed that it was not finding any segments to delete. The only problem
I could find was the threshold. After "removing" this threshold, I was able to
get some clear segments again. I personally cannot explain why the check is
there at all. Maybe there is a good reason but the comment above it didn't help
much.
So, here for completeness the threshold: 1358164666 (aka: Mon Jan 14 12:57:46
CET 2013)
And here are the output of lssu and lscp:
$ lssu --all
