Running lustre 2.4.0-19chaos we recently had several OSS nodes crass on the following BUG:

kernel BUG at fs/jbd2/transaction.c:1033

They were all in an ll_ost_00_0?? thread with the same backtrace:

__ldiskfs_handle_dirty_metadata
ldiskfs_free_inode
ldiskfs_delete_inode
generic_delete_inode
generic_drop_inode
iput
osd_object_delete
lu_object_free
lu_object_put
ofd_object_put
ofd_destroy_by_fid
ofd_destroy
ofd_destroy
ost_handle
ptlrpc_server_handle_request
ptlrpc_main

The failures were on the secure network, so I can't upload logs.
