But... As the APARs indicate, it is typically the case that TSM helped
identify a site configuration/service problem, which needs to be pursued,
as it can affect all applications running on that system.

DNS lookups should be almost instantaneous in a well configured system.
(Having an unresponsive DNS server's IP address in a DNS servers list
can result in a four-second failover delay before rotating to the next
address in the server list.)

I would urge pursuit of the underlying problem.
