We are using Dsnmasq for several years as our primary DNS and DHCP server
Today, we experienced serveral crashes for example :
Sep 14 09:53:44 VcacDebDNS1 kernel: [3801156.651129] dnsmasq:
segfault at 50 ip 000000000041d5d8 sp 00007ffeda119230 error 6 in
sometimes 10 seconds after restart
the server works again but we do not know the exact reason causing this
the info we got i that dnsmasq.leases file was exactly 512 lines log at the
time of the crash
(we deleted the file for restarting the services)
can these be related ?
are there some config parameters to support that number of devices ?
Can the cache_limit parameter have some effect ? (actually to the default
and there are 70 DNS queries per second)
