dns query id not changing

[straightflush at gmail.com]

Hello,

I am experiencing an issue on redhat 8 with the resolver where the
"Transaction ID" in the dns query is not changing.  This is causing our
firewall to drop packets b/c a second dns request is coming in with the
same udp port, ip, and transaction id.  The firewall still has the
first dns request in its state table and is causing the firewall to
drop the susequent packets due to this.

Has anyone encountered this issue (possibly the resolver in glibc 2.2?)
and know if there is a workaround?

thanks
adam
