<p>Hello Chris,</p>
<p>in general, these errors are benign. They are part of standard
midPoint approach to serializing access to the repository.</p>
<p>They should become a concern only if there are too many of them.
This can be observed by looking at task's Internal performance tab
(local tab performance), or Internals configuration ->
Performance tab (global, node-wide performance counters). There is
something like this (exact formatting depends on midPoint
version):</p>
<p><img src="cid:part1.11178507.CA54BEF0@evolveum.com" alt=""></p>
<p>And, in the new PostgreSQL-based repo (in 4.4) we assume we will
loose the DB transaction isolation level, so there should be less
of these retries. Most probably. :)<br>
</p>
<p>Best regards,<br>
