</span>Hi Ciro,<br>
<br>
Sadly your trace is interleaved with a bunch of other queries which make it<br>
harder to see what is going on.<br>
<br>
The trace for '<a href="http://2.centos.pool.nto.org" target="_blank">2.centos.pool.nto.org</a>' stops in the middle:<br>

How did you gather or select the trace output? Is it possible you missed some output?<br>
<br>
Also, what Lua scripts do you run? Might these be interfering in some way?<br>

I disabled that for this trace capture, I also disabled the Lua script just in case, but the timing is roughly the same.
