<p class=MsoNormal>Hi :-)<br>
<br>
<br>
I installed pdns-static-2.9.21-1.i386.rpm on RHEL4 (2.6.9-34.0.1.ELsmp #1 SMP
Wed May 17 17:05:24 EDT 2006 i686 i686 i386 GNU/Linux) together with the <a
href="http://test.com">test.com</a> sample found on <a
href="http://powerdns.com">powerdns.com</a>.<br>
<br>
When I run /etc/init.d/powerdns monitor, sometimes it runs:<o:p></o:p></p>
<p class=MsoNormal>Apr 28 14:57:09 gmysql Connection succesful<br>
Apr 28 14:57:09 About to create 3 backend threads for UDP<br>

Apr 28 14:57:10 Done launching threads, ready to distribute questions<o:p></o:p></p>
<p class=MsoNormal><br>
And sometimes it crashes on sig11:<o:p></o:p></p>
<p class=MsoNormal>% Apr 28 14:56:56 Got a signal 11, attempting to print
trace:<br>

Apr 28 14:56:56 [0x829b5a8]<o:p></o:p></p>
<p class=MsoNormal><br>
When it runs, sometimes it answers immediately, sometimes after seconds:<o:p></o:p></p>

I found some things about CS, but the server is not that busy:<o:p></o:p></p>

Since pdns seems to be able to run very well, so any suggestions what I can do
about this?<br>
<br>
<br>
Thanks<br>
