<p>Hello,</p>
<p>In our pgpool configuration we set parameter
CLIENT_IDLE_LIMIT=300.</p>
<p>As a result of that, our app developers periodically receive the

<p>So they see an ERROR message and it confuses them.<br>

<p>Could you tell me if this is really an error or if it can be
ignored?<br>
</p>
<p>If this is NOT a really error, why is it displayed so suspicious?<br>
</p>
