mirror/stripe freezing under FreeBSD 5.5

[Rex Roof]

is blocking reads or something.   I'm not sure.

my mirrors are completely built:

$ gstripe status
           Name  Status  Components
stripe/bigstripe      UP  mirror/mirone
                         mirror/mirtwo
                         mirror/mirthr
$ gmirror status
        Name    Status  Components
mirror/mirone  COMPLETE  ad4
                        ad8
mirror/mirtwo  COMPLETE  ad6
                        ad12
mirror/mirthr  COMPLETE  ad14
                        ad16

and here are my device listings:

as you can see, they say DIRTY.   a few seconds later they changed to CLEAN.
I'm noticing now that they're changing back and forth rather frequently.
perhaps once a minute;  much more often than the freezing is happening.
