VMFS is a journaling file system where it keeps track of changes not committed to the disk yet. These journals are later replayed by the hosts.
The journal/HB block leaks happen on VMFS Filesystem in the case of storage connectivity problems while closing volume.
invalid argument
status indicates that the content of the heartbeat region is not correct. The subset of files managed by that region is likely to have been locked by a single host that crashed at some point (although other reasons are possible).Note: In a rare scenario, one can have a situation where two hosts that share a common resource tries to replay a given journal in parallel. This can cause the journal not to be completely replayed and can cause certain locks (taken on the resource) to be lost. This in turn can cause a VM on the host to get hung or inaccessible.
