SIGSEGV 11 segmentation violation

           Summary: SIGSEGV 11 segmentation violation
           Product: Tomcat 3
           Version: 3.2.3 Final
          Platform: Sun
        OS/Version: Solaris
            Status: NEW
          Severity: Critical
          Priority: Other
         Component: Unknown
        AssignedTo: tomcat-dev@jakarta.apache.org

Hello,

Many times when I tried to access my web pages I will get the following series 
of errors and utlimately tomcat crashes. I use Tomcat 3.2.3 as web server and 
servlet engine. Right now our project is in testing mode. 

I observed this exception will occur when user clicked various pages one by one 
immediately. Is is smething becasue of poor request handling when user hits on 
multiple pages simulatelously (randomly)

Regards
Suraj

The details of error is  as follows
