RES: Bind 9.6.1 stops after few hours.

[Laurence Stendard]

Hi Rob,

I could not reproduce this behavior on my Linux lab machine using queryperf. As Jinmei pointed this seens to be a Solaris thing.

I still could not reproduce the problem I faced on my own production DNS...

Thanks for your post!

Laurence

I don't know if this is the same as what Laurence is seeing.  Testing
9.6.1 on Solaris 10/sparc, with a local build (THREADS, no MEMFILL,
openssl 0.9.8k) the server stops responding to queries made from the
network (LAN), until a local query comes in (dig @localhost ...).

To reproduce this:

queryperf -> 9.6.1 acting as a mostly recursive server (haven't tested
	     with a server configured as authoritative-only).

The server stops responding during a 30 second queryperf run.  Running
a script on the name server with 'dig @localhost...' once per second
wakes the system up and the server continues answering queries made
via the network.

Have not tested either of these changes, yet.  I have not tested the
packages from sunfreeware, yet.
