p.s am not talking about monitoring tools like caccti,nagios etc.

thanks
If this is only a problem when you are not in front of the server, you can either always stand in front of the server or you can tell us what you do while standing in front of the server that keeps the spikes from happening or being a problem. Then maybe we can help you write a script that would do what you do while standing in front of the server that keeps it from being a problem (even when you're not standing there).

CSERVER(8)						      System Manager's Manual							CSERVER(8)

NAME
cserver - To start the Chinese server. SYNOPSIS
cserver [-f file ] [-s file ] DEFAULT PATH
/usr/local/bin/cWnn4/cserver DESCRIPTION
During Chinese input, cserver provides the services (such as conversion services) and resources (such as dictionaries, grammar files etc.), required by the users (front-end processors). The input environment is provided by the front-end processor (cuum), which sends its request to the cserver, which subsequently performs the service and return the result back to the front-end processor. Normally, once the system is up, fork() will be executed and the server runs as a background process. The startup of cserver can be set in "/etc/rc" to be executed automatically in the Unix system. When the "cserver" command is executed, all the settings in the initialization file "/usr/local/lib/wnn/zh_CN/cserverrc" will be read and the corresponding initialization operations will be performed. Besides, all resources such as dictionaries and usage frequency files of the clients will be maintained by the cserver. Refer to cWnn man- ual for details on "cserverrc". If the user happens to start up cserver after it has already been started, an error message will be given. Refer to cWnn manual for the error message. OPTIONS
-f file file is the specified initialization file for the server. If this option is not specified, the default initialization file "/usr/local/lib/wnn/zh_CN/cserverrc" will be read. -s file file is the specified logfile of cserver. All error messages will be directed to this specified logfile. When file is specified as "-", (eg. cserver -s -), the error messages will be sent to the standard error output. NOTE
1. The command options inside [ ] shown in the Command Format indicates that they are optional. 2. If they are not required, "cserver" alone is sufficient to start up the Chinese server. 13 May 1992 CSERVER(8)
