Key: CACTUS-60
Summary: Clustered servlet test results are not accurately reported
Type: Bug
Status: Open
Project: Cactus
Components:
Framework
Fix Fors:
1.7
Versions:
1.5-beta1
Assignee: Cactus Developers Mailing List
Reporter: John Kristian

Environment: Operating System: Windows XP
Platform: PC
Description:
If a servlet test suite is deployed to multiple servlet containers in a
cluster, and invoked by HTTP requests via a load balancer that does round-robin
or similar routing of HTTP requests that have no session cookies, test results
are not accurately reported. Initially, tests are reported to have failed
(inaccurately); at this time, exceptions similar to the one below will be
thrown in some (not all) servers. Later, the results of one test may be
attributed (inaccurately) to other subsequent tests.
The problem does not occur in a non-cluster configuration, nor in a cluster
with only one server up.
I'm using jakarta-cactus-13-1.5-beta1, with WebLogic 8.1 SP1 on Windows XP.
Here is an excerpt from a server log:
