From the OSS console:

This issue caused the later 56ic to fail as well. According to 56ic's debug log, the -ENOENTs likely came from ofd_attr_get()'s "else" block.

error: cb_find_init: lstat failedfor /mnt/lustre/d0.sanity/d56w/dir1/file3: Cannot allocate memory (12)
error: find failed for /mnt/lustre/d0.sanity/d56w.

Looks like LU-3092.

Definitely, I got such/same auto-test failures and as explained in LU-3092 I rebased on top of LU-3057 changes and everything run fine then.
