Subject JSP & Servlets
Date Mon, 26 Jun 2000 15:25:31 GMT
 Apache 1.3.12
Tomcat 3.1 on Solaris 2.6
JVM 1.2.2_5a started with native threads

We got the following problem when a servlet is used with a JSP.
The application runs OK for a while but at a certain point we the following error.
After this error both the JSP and the servlet involved don't run correctly anymore unless
the JVM is restarted.
Can any one shine a light on this ?
Thanks and regards Xander Heemskerk
