xfs_irecover falls into endless loop reading from xfs_db

[dbmill]

Hi,
xfs_irecover launched as follows,
./xfs_irecover -D /dev/miss-bitrix/usrlv -o /mnt/iblock/

It eventually hangs in endless loop,

read(6, "", 0) = 0
poll([{fd=6, events=POLLIN}], 1, -1) = 1 ([{fd=6, revents=POLLHUP}])
ioctl(6, FIONREAD, [0]) = 0
