db2icrt/db2idrop hangs when executing db2isrv

Problem(Abstract)

When using IBM DB2 for Linux, UNIX and Windows, running db2icrt/db2idrop against an DB2 instance name results in db2icrt/db2idrop process hangs when it is executing db2isrv in child process.

Symptom

db2icrt/db2idrop hangs when executing db2isrv

Cause

DB2_db2instance1_1 60045/tcp 
DB2_db2instance1_2 60046/tcp 
DB2_db2instance1_END 60047/tcp

Example 2:
DB2_instance2 related port entries are in wrong order:

DB2_db2instance2_1 60001/tcp 
DB2_db2instance2_2 60002/tcp 
DB2_db2instance2_END 60003/tcp 
DB2_db2instance2 5914/tcp

Resolving the problem

1. Remove DB2 port entries related to the instance name in /etc/services file

2. Run db2icrt/db2idrop command again.
