More data: on the bare-metal host, $HOME is a separate (/home) filesystem.
If I move the home directory to /usr, the problem dissapear.

/dev/raid2h on /usr type ffs (nodev, local)
/dev/raid2i on /home type ffs (local, with quotas)

file system: /dev/rraid2h

so maybe the large bsize/fsize is the problem ?
