DB2 FOR LUW / DB2FORLUW / A50 - DB2

db2sysc is a setuid process.  On Linux the PR_SET_DUMPABLE 
setting must be modified in order to allow the generation of a 
coredump in the case of a crash.  Currently this setting is 
modified during the crash processing itself.  In some cases a 
second error may occur before reaching the point where 
PR_SET_DUMPABLE is modified, with the result that no coredump 
will be generated. 
 
This may impeded the diagnosing of DB2 crashes, which frequently 
require a coredump to analyze the memory contents at the time of 
the crash.  Coredumps are normally generated by default, and the 
cause of the omission may be difficult to understand.

* This is a serviceability improvement only.  Upgrade to DB2   * 
* Version 10.5 Fix Pack 7 or implement the workaround.         * 
****************************************************************

A workaround is to set the system wide setting fs.suid_dumpable 
value to "1", i.e. 
sysctl -w fs.suid_dumpable=1

Problem first fixed in DB2 Version 10.5 Fix Pack 7
