A component of the PetaLibrary/active service (ZFS, providing storage for beegfs-storage, part of the BeeGFS parallel file system) is experiencing a load-induced race condition. When the race condition results in an error, a write fails with an error message like "Bad address".
This issue has previously been reported (and resolved) upstream.https://github.com/zfsonlinux/zfs/issues/8640
This fix is available in the 0.8 branch of ZFS. We are planning an update from our currently-deployed ZFS 0.7.13 to resolve this issue. We will provide updates here as more information becomes available.
