[Pdns-users] 2.9.8 & signal 11

[Ole Gjerde]

Hi,

I just setup pdns 2.9.8 and it "mostly" works :)

PDNS: 2.9.8 using static rpm from the pdns website
OS: RedHat Linux 7.3

When I run it, things seem to work pretty well, and it's plenty fast enough 
for our purposes.  Unfortunately after a while(less than 5 minutes) it will 
start to segfault(see log below).

They seem to come in groups with often 5-10 in a row, then it will work fine 
for a couple minutes, then segfault a bunch in a row again.  There is nothing 
in the logs to indicate any problems before the crashes.  It only seem to be 
happening when I run it "live", when run as a test (using querypref to test 
it) it works great getting 4500 q/s on a AMD K6-2 400MHz(mostly testing 
cache).

I'll probably test a self-compiled one later tonight and see how that one will 
fare.

My configuration is about as simple as possible:
launch=gmysql
gmysql-dbname=pdns
gmysql-host=127.0.0.1
gmysql-password=$PASS
gmysql-user=pdns
log-dns-details=yes
log-failed-updates=yes
logging-facility=0
setgid=pdns
setuid=pdns

Thanks,
Ole Gjerde
