postdrop fail to create file after upgrade to 5.0.3

[uxbod]

As root /opt/zimbra/libexec/zmfixperms.

same issue after upgrade from 6.0.6 to 6.07
i do not run /opt/zimbra/libexec/zmfixperms
as all the rigths are ok.
then i realised that during upgrade postdrop was not stopped.

in fact after

ps ax|grep postdrop
 8838 pts/1    S+     0:00 grep postdrop
18558 ?        S      0:00 /opt/zimbra/postfix-2.6.6.2z/sbin/postdrop -r


$  zmmtactl stop

 ps ax|grep postdrop
 9449 pts/1    S+     0:00 grep postdrop
18558 ?        S      0:00 /opt/zimbra/postfix-2.6.6.2z/sbin/postdrop -r

here is the issue:

===>>> postdrop survives to zmmtactl stop; <<<<=====


i killed it and start zmmtactl again. now i get rid of that annoying message
