[Pdns-users] Pdns 2.9.20 - 21 svn crash

[Marco Chiavacci]

Hi,

we have two dns server runninng bind 8 with a lot of zones (near 640000) and
we finally decide to migrate to pdns + bind backend.
All seems really fast and service comes up in 4-5 minutes vs. 2h40m with
bind8 with the same zones and named.conf.
But suddenly (from 10m to 1h30m not more) and not in a specific situation,
process dies with this trace:

Oct 27 14:24:31 dns pdns[29788]: Got a signal 11, attempting to print trace:

We also compile the pdns-2.9.21-svn.20061001.897 but the crash is the same.
This situation is similar in redhat (centos 4.4 x86_64) or debian (etch
x86_64)distribution in the same machine (dell 1950 with 8 giga ram), whith
compiled o rpm version.
For a try I convert, with zone2sql, to gmysql and it seems to run stable,
but, for now, we cannot use this backend because the provisioning software
wich uses old bind zone files.
