We ran our web app on Tomcat 4 on an AIX 5.3 box Java 5_64 with no issues
for 2 years.
We recently upgraded to Tomcat 6 and we are seeing some unusual problems.
1) After working for 2-3 days with heavy load One of our functions errors
with
java.sql.SQLException: java.io.IOException:
java.net.SocketException:
There is no process to read data written to a pipe.
2) Jsp classes that were working properly start throwing Exceptions like
ClassCastException
Resolution is only by clearing cache and re-starting.
We are thinking maybe the OS needs and upgrade and we need to be on Java
1.6
Would appreciate if anyone else had similar experience - what was
resolution.
