Hello,

I got on 2 out of 15 (for now) logical volumes (all XFS filesystems) the
following error :
Filesystem "dm-17": XFS internal error xfs_trans_cancel at line 1138 of file
fs/xfs/xfs_trans.c.  Caller 0xffffffff803e20e0

The first time I immediately thought about a memory problem, but for now this
bug only happened on 2 volumes, and not the most busy ones. Moreover, there is a
NFS server running on the same server, intensively using the page cache (for
files) and thus using the memory.
What is curious is that the shutted down volume is not corrupted (I mounted it
to replay the log, then unmounted and xfs_repair -ed it without finding any 
error).

The serveur is running Linux kernel 2.6.21.5, xfsprogs 2.9.3.
