[Gluster-devel] Memory Leak Strikes Again

I have just noticed that the memory leak on the root file system appears
to still be occuring. The only things I have changed are that I have now
removed the "direct-io-mode=off,log-level=NONE,log-file=/dev/null" mount
parameters, so it appears to be related. The process grows to over 350MB
during a single test pass.
The operation that causes major leakage is making the initrd for Open
Shared Root (much more involved than normal mkinitrd, as it makes
repeated calls to the rpm database, which, in this instance, is in
SQLite format because BDB flatly refuses to work on GlusterFS). Leakage
is approximately 1MB every 5 seconds during the operation, and GlusterFS
uses 100% of CPU while the operation is occurring (which is in itself a
tad worrying even if it is running on a 1.6GHz Atom 330, which is not
exactly an underpowered machine). rootfs is AFR, but the machine is
operating standalone (no peers connected).
I have just put it back as it was (mounted with
and sure enough the leak disappeared. The CPU usage is also down to a
much more reasonable 25-30%.
Should I bother with a bugzilla report, or is this already a known issue
