Hi,

>From the release notes for R14B04:
---
OTP-9423  Fix emulator deadlock in ets:delete on tables with write_concurrency
              caused by race with concurrent process that tries to do
              other operation on the same table. Does not apply to ordered_set.
              Bug exist since R14B.
---
Is there any remote possibility that this issue could affect tables
without the 'write_concurrency' option set to true?
We are experiencing something that looks like an ets deadlock with
R14B03, but we don't have any tables with write_concurrency, only
read_concurrency.

Regards
Jonas
