[chef] couchdb leaving deleted file descriptor turds?

hi. i'm running couchdb 1.0.1, chef-server 0.10.8-1 on ubuntu 11.04.
upon seeing my file system get a bit full, i sniffed around lsof, and
see a bunch of couchdb open file descriptors in a deleted state. to
bring my file system usage down, i bounce couchdb.

is this known? a bug? a misconfig on my part?

[snip many]


after restarting couchdb (and chef-server), lsof is clean and got disk
space back
