squid -k reconfigure does not work with cache_effective_user on 3.1.0.17

Hello all,
 
No matter what I do, I cannot get squid reload with 3.1.0.15.
 
Directory permissions and everything is properly set for cache_effective_user. Squid starts at boot with initscripts, opens a low-numbered port. It works fine when run as root, and switches to cache_effective_user as expected (child and spawn nsca_auth processes).
 
However, I cannot send it a reconfigure signal with 'squid -k reconfigure' or 'kill -HUP'... when i am logged in as cache_effective_user.
 
I can send a kill signal to apache for example (running under the same uid).
 
ERROR: Could not send signal 1 to process 7467: (1) Operation not permitted
 
RHEL 5.4 x64
SELinux disabled
 
 
I tried setuid /bin/kill but that did not work either.
 
This was working fine before with 2.6. Any ideas how to reload squid or what happenned?
 
Thanks!
 
J
 
PS: Same issue with 3.1.0.17 too.
