out of memory

           Summary: out of memory
           Product: Tomcat 4
           Version: 4.1.18
          Platform: Other
        OS/Version: Other
            Status: NEW
          Severity: Critical
          Priority: Other
         Component: Connector:Coyote JK 2
        AssignedTo: [EMAIL PROTECTED]
        ReportedBy: [EMAIL PROTECTED]


Hi,

I am having "out of memory" problems. Our configuration is like this.

webserver->firewall->tomcatserver(LAN)

The out of memory problem only occurs between the webserver/tomcatserver - ie 
the coyote jk2 connector. I can still access and use tomcat internally from our 
LAN using the Coyote HTTP Connector. THis error is intermittent and occurs 
sometimes. However, when it does occur we cannot access tomcat via our external 
(internet) users until we restart tomcat.

Refer log below:
