Screenshot showing actual errors

Description of problem: When relabeling a VM with 256MB (by means of placing the /.autorelabel file) some "Out of memory" errors are shown (please see attached screenshot).

I first encountered this with a CentOS 6.3 VM and eventually with RHEL6.3.

Version-Release number of selected component (if applicable):


Steps to Reproduce:
1. Install RHEL 6.3 
2. After installation, change the VM memory to 256MB
3. touch /.autorelabel & restart
Actual results:
Out of memory errors are shown

Expected results:
Just the relabeling related messages

Additional info:

free -m (output):

             total       used       free     shared    buffers     cached
Mem:           243         93        149          0          6         42
-/+ buffers/cache:         44        198

A potential fix for this would be to no longer run genhomedircon on systems with limited memory.

free | awk '{ if ( NR == 2 ) { if ( $4 < 25000 ) { exit ; }}}'
/usr/sbin/semodule -Bn

This request was not resolved in time for the current release.
Red Hat invites you to ask your support representative to
propose this request, if still desired, for consideration in
the next release of Red Hat Enterprise Linux.

I think that minimal requirements for rhel6 specify 512MB of RAM.
