<DIV><FONT face=Arial size=2><SPAN class=209560819-30062003>Hi, I am using
PowerDNS on a couple of identical servers. In my log messages on each machine I
am noticing restarts by pdns based on it receiving a signal 6 or signal 13. This
happens approximately once or twice each day seemingly at random times. The
boxes are also not being hit with dns queries at this time. The install is the
Redhat 2.9.7 static RPM and the machines are running RedHat 7.3. Here's the
output from the log files</SPAN></FONT></DIV>

<DIV><SPAN class=209560819-30062003><FONT face=Arial size=2>The signal 13
messages basically prints out the same information without the trace etc. I may
try a source build of 2.9.9 and see if the issue goes away. PDNS is being
launched with --daemon and --guardian=yes via the init.d script. It uses the
gmysql backend connector. Has anyone else seen these messages?
Thanks</FONT></SPAN></DIV>
