<div class="moz-cite-prefix">Did you try 5.6.0-SNAPSHOT? <br>
Many possibly related bugs have been fixed there, and it's about
to be released as 5.6.0.Final.<br>
On the other hand, if you could help us identify your issue by
providing some more context,<br>
we'd try to make sure that a fix is included in 5.6.0.Final<br>
Thanks<br>

<div>It looks like you are using the experimental
multi-threading mode, I'd recommend you disable that, and
try the latest 5.6.0.SNAPSHOT builds if you have problems.</div>
