Hi,
On Resin 4 (not 3.1), in the case of a web-app-deploy with nested
web-app configuration, hitting the default idle-time (2 hrs) apparently
results in a webapp restart on the next request. Configuring a negative
idle-time on web-app-default seems to work around the issue.
Configuration example:
<web-app-deploy path="applications"
expand-directory="applications/.expand"> <web-app
context-path="/xxxxxx/${system['xxxxxx.context.path.current']}"
root-directory="xxxxxx"/> </web-app-deploy>
Stack trace (for Resin 4.0.41) to DeployController.restartImpl() in
attachment.
Best regards, Tom
