atariad memory error, do I have to worry about?

[Harald Schmalzbauer]

Hello,

after I growfs'd my /usr label I had softupdates inconsistencies.
I dumped /usr and newfs'd/restored it with the new (bigger) label to be on the 
safe side.
While restoring I got this error:

FAILURE - out of memory in ata_raid_init_request
g_vfs_done():ar0s1e[WRITE(offset=3864918016, length=2048)]error = 5

What dows that mean?
FreeBSD 6.2-RELEASE-p5
