[RCU] poppassd hang

I'm using roundcube and poppassd as the plugin for the change password. It was running fine in CentOS 5.6 using poppassd rpm. However, in CentOS 6 there is no rpm yet so I compile it following the procedure on this sitehttp://netwinsite.com/poppassd/#Unix_Installation. The problem is it doesn't quit after after the newpass. Password was successfully change but since it doesn't exit/quit, then the pid is stuck on the background resulting to passwd defunct process. User is confuse because there is error in roundcubemail but the password was change. Error might be result of the poppassd not exiting.

Just wondering if someone from the list has manage to fix this issue or at least use a rpm for CentOS 6 or RHEL 6.

TIA,

Nelson
