           Summary: blktap dies, random ENOMEM in xs clients
           Product: Xen
           Version: unstable
          Platform: All
        OS/Version: All
            Status: NEW
          Severity: major
          Priority: P2
         Component: Tools
        AssignedTo: xen-bugs@xxxxxxxxxxxxxxxxxxx
        ReportedBy: pascal@xxxxxxxxx

I noticed blktap dies when I remove a block device from the VM,
and that some xs clients get ENOMEM at the end of a transaction.

Seems to come with patchset 15178 that introduced an eprintf via

Xenstored closes STDERR, a client gets connected on fd 2, then another
inc/dec error leads to eprintf triggered from domain_entry_fix().

The client dies reading '[ERR] domain_entry_fix: ...'

I quickly commented the close(STDERR_FILENO) as a test and this behaviour
