timeout for query?

[Pavel Urban]

Hello,

we're having problem with PIX firewalls closing UDP 'connection' after 
30 seconds. Is there a limit to which a response for query must be sent?

sample: (10.7.9.10 is our DNS, doing recursive query somewhere outside. 
It takes some time, so the 'connection' to client 83.208.117.4 is closed 
prematurely)

04:00:16 Teardown UDP connection 404532028 for outside:83.208.117.4/2200 
to dmz:10.7.9.10/53 duration 0:00:30 bytes 276
04:00:16 Deny udp src dmz:10.7.9.10/53 dst outside:83.208.117.4/2200 by 
access-group "acl_dmz"
04:00:16 Deny udp src dmz:10.7.9.10/53 dst outside:83.208.117.4/2200 by 
access-group "acl_dmz"
04:00:16 Deny udp src dmz:10.7.9.10/53 dst outside:83.208.117.4/2200 by 
access-group "acl_dmz"
04:00:16 Deny udp src dmz:10.7.9.10/53 dst outside:83.208.117.4/2200 by 
access-group "acl_dmz"

Thanks!
