[Pdns-users] PDNS-Recursor Segfaults

Hi All - I'm experiencing an issue that I am unsure if it is a bug or
just something I need to adjust on my systems to account for.
I have 2 servers, both running pdns_recursor (3.5.3) on Centos 6.5,
installed from epel repository. The recursor is only listening on
localhost on each system.
I am experiencing somewhat random crashes of the recursor with the
kernel: pdns_recursor: segfault at 200001fc8 ip 0000000000472780
sp 00007f3f9c03f690 error 4 in pdns_recursor[400000+111000]
Both servers have a large number of ip addresses bound to them, in the
range of 3-4k. I was able to replicate the segfaults on one of the
servers by adding additional ip addresses. When I got to around 4k ip
addresses the recursor simply would not even start, just segafulted
right away. I was able to get it to start again, by removing some ip
addresses, so i know it has something to do with how many addresses I
have bound the server.
Any body have an ideas what I can do to correct this problem? I really
don't see a reason why the recursor would care how many ip addresses I
have on a system.
