Under Tomcat 3.2.1,Apache 1.3.12,mm.mysql.2.0.4,mysql 3.3.28,NT 2000
On one machine when it is restarted some jsp pages work correctly while
others
give an error. See below for the full error. The pages are generated from
jsp from
data in a mysql database. Only by carefully restarting the apache, tomcat
and
mysql services in the correct order with a delay between the restarts do
the pages
start working correctly. The pages will then work correctly until the
server is restarted.
I'm at a bit lost as to which component is actually causing the trouble !
The fault
does not appear on a test machine that does restart and work without user
intervention
Because the main server is under load, could it be that the jsp pages are
attempting
to access resources that are not yet available causing a permanent failure ?
