This has been reported before, and we've patched the system so that the
error reported is better. In HEAD we also patched it so that the system
would automatically retry a number of times if the problem is
ERROR_SHARING_VIOLATION (or something like that). That patch was not
backported to 8.2 due to lack of testing -- the original reported did
not come back to try the patched version.
If you want to try, the patch is here:

Let us know how it goes. If your problem is easily reproducible and the
patch makes it go away, we would consider back-patching the fix.
Thanks.
