<p class="MsoNormal">Hi!<br>
<br>
This errors does not mean that foreign key usage is broken. This means that there is a mess with transactions. As you paste small piece of trace it is hard to say why this happen, but during my work I saw such errors and resolve them. And probably you need
to revisit your unit tests.<br>
<br>
Please, send me email directly with links for traces, does this happen on master branch, does it happen on one of your changes - it is hard to guess.
