Description of problem:
After applying RHSA 2002:197-06 "Updated glibc packages fix vulnerabilities in resolver" our Domino servers freeze. On one (mail server), the server freezes when 
another mail server connects to port 25 and the SMTP task presumably calls the resolver. On the other (application server), the server will run as long as the Event 
Monitor is not started. Once the Event task is loaded, it freezes immediately. 

Version-Release number of selected component (if applicable):


How reproducible:
Always

Steps to Reproduce:
1. Use RHN to update glibc to glibc-2.2.5-40
2. Reboot server
3. Try to start Lotus Domino server
	

Actual Results:  All Domino server processes freeze approximately one minute after Domino is started. There are no log entries or other diagnostics. The server 
processes simply freeze up and have to be kill -9'ed.

Expected Results:  Domino server should have run sweetly, as usual.

Additional info:

The problem was masked by the usual long uptimes of the Domino servers. We used RHN to apply RHSA2002:197-06 on 4th October. However, installing the fix only 
updates the files - the running Domino processes in memory are still linked with the old glibc code, so nothing goes wrong. However, we rebooted both servers on 
Sunday 27th October and immediately struck trouble. Because of the long delay, we wasted time investigating other system configuration problems before reinstalling 
the glibc*.i386.rpm files from the original RH 7.3 CD's, which fixed the problem. However, now we have the original resolver vulnerability. . .

Bug is both high severity - we lost email for our entire company for four days - and relates to security
