Our Server is up and running fine for Intranet users but sometime for Internet users it goes down and we have to restart IIS.I have done lot's of serach and research on this topic and found one note from SAP that it may be due to the following reason:Active Requests exceeds the default thread count which connector can connect to Tomcat and they mention the Jakarta Connector version..I am unable to check which Jakarta connector version we have.Can any one please help me finding the Jakarta version or help regarding the issue.
we are using Tomcat 5.0.27 which is connected to IIS 5.0 (Windows 2000 Server) using Jakarta connector(isapi_redirector.dll)
From ASAPI connector log i see the following errros:
