You might be affected by this Werk if you use the mk_db2 agent plugin on AIX.

mk_db2.aix use a login shell since Werk #17480. This means that anything written to stdout in /etc/profile will be part of the db2 sections. This of course will crash the check as the checks do not expect random data included in their sections.

This Werk now applies some redirecting to remove the welcome message.
