Semaphores getting created, thus blocking start of Webserver ctl

I am using Solaris 9 system and IBM HTTP Server 6 for my webserver. Semaphores with webadmin and root privileges are getting created more often and blocking the start of webserver ctl instances. I use 'ipcs -s' to list them and 'ipcrm -s' to kill them one by one.

But even after killing, a new batch of them reappear again. Plz help !!

smcwebserver - manage the server for the Sun Web Console SYNOPSIS
/usr/sbin/smcwebserver subcommand options DESCRIPTION
The smcwebserver utility manages the Sun Web Console server. Sun Web Console is a browser-based interface that performs systems management. System administrators can manage systems, devices and services from the console. When the console webserver is running, you can view the console by opening a browser and pointing to: https://host:6789 host is the machine where the console has been installed and the console server is running. SUBCOMMANDS
The following subcommands are supported: disable Disable automatic start or stop during system boot or shutdown. Until the administrator reruns the script with the smcweb- server enable subcommand the webserver can be started/stopped only when the administrator executes the script manually using the following command: # /usr/sbin/smcwebserver [start | stop] enable Enable the webserver to startup automatically during subsequent system boot and gracefully stop during system shutdown. restart Stop and subsequently start the console webserver. The format of the restart subcommand is: restart [-U username] start Start the console webserver. The format of the start subcommand is: start [-U username] stop Stop the console webserver. status Display status of the console webserver. The format of the status subcommand is: status [-p] OPTIONS
The following options are supported: -U username | --username usernamThe user identity to run the server as. Once the server has successfuly started under the specified iden- tity, all subsequent starts will automatically be done under that identity until you change it via this option, or by changing the com.sun.web.console.user configuration property via the smreg(1M) command. The default is to run the server under the "noaccess" identity. -p | --parseable Display non-localized output suitable for programmatic parsing. If the server is running, the output will be: running=yes If the server is not running, the output will be: running=no -h | --help | -? Display the usage statement. -V | --version Display console version information. EXAMPLES
Example 1: Displaying the Usage Statement The following command displays the smcwebserver usage statement: % smcwebserver --help Example 2: Determining if the Server is Running The following shell command will start the server if it is not already running. ans=`smcwebserver -p | grep running | cut -d"=" -f2` if [ "$ans" = "no" ]; then smcwebserver start fi ENVIRONMENT VARIABLES
