amavisd stops after reload

[Martin Fuxa]

after upgrade from 2.6.6 to 2.8.0 stops working
amavisd reload
same with 2.8.1-rc1

On terminal prints
Signalling a SIGHUP to a running daemon [4756]

in log
Jun 11 23:12:53 anta3 amavis[4756]: (!)Net::Server: 2013/06/11-23:12:53 
HUP'ing server

but no one instance isn't runing after reload.

same with kill -s SIGHUP $pid

system is CentOS release 5.9 (Final), in up2date state.
Net-Server version: perl-Net-Server-0.99-1.el5.rf

something is wrong?
