AIX APAR IV22062 describes a situation in which a hang or a crash might occur 
in DB2 versions earlier than DB2 10.1. At the time of this document's initial 
publication, all Tivoli Storage Manager servers are running a version of DB2 
that is affected. The DB2 product provides a techdoc for all known operating 
system issues. This techdoc should be referenced by Tivoli Storage Manager 
users to determine if they might be exposed to problems based on the operating 
system level:

This AIX APAR addresses a problem causing private memory corruption on all DB2 
versions prior to DB2 Version 10.1. Only systems running AIX 6.1 TL06 SP8, TL07 
SP4, or AIX 7.1 TL01 SP4 are vulnerable, with corresponding bos.rte.libc levels 
of 6.1.6.18, 6.1.7.15 and 7.1.1.15. The common symptoms are a DB2 server hang 
or crash due to malloc heap corruption, with the trap file diagnostics 
frequently including malloc or initializeXalan functions.
