I am trying to user the command db2star in my new DB2 Express instance and I receive:

SQL1042C An unexpected system error occurred.

Looking at db2diag.log I got:

I installed DB2 express in my MAC Machine (OSX El Captain) using the following guide:

I'm also using DB2 V10.1 on my mac. I have used it since mac OS 10.6 snow leopard. And I encountered same situation recently and resolved with the same way that Renato tried. Just sharing the capture from my dirty note.

After doing

$ sudo chown db2inst1 /Users/db2inst1/sqllib/adm/*

I could do 'db2start' successfully.

A more up-to-date for Installing DB2 on Mac OS El Capitan is available.

This is the crucial step:

Enable OS authentication. (You need to be an admin user to run these commands):

     cd /Users/$(whoami)/sqllib/security
     sudo chown root /Users/$(whoami)/sqllib/security/db2ckpw
     sudo chmod u+rxs /Users/$(whoami)/sqllib/security/db2ckpw 
     sudo chmod o+rx  /Users/$(whoami)/sqllib/security/db2ckpw

Solved. Just run:

sudo chown db2inst1 /Users/db2inst1/sqllib/adm/*

where "db2inst1" is your DB2 user.
