Hi,

I have copied activiti-explorer and activiti-rest war files into tomcat. It worked initially, but after few deployment tomcat is not starting. I can see below log messages

Do you know why it is redeploying those processes?

Does it do anything else? No Exception?

I am experiencing something similar on CentOS with Activiti 5.16. Initially thought that restarting Tomcat did not succeed, but it just takes a really long time. I am still investigating, but the Activiti deployment was clean, ootb.

Upon shutdown I get things like this in the logs:

I am experiencing something similar on CentOS with Activiti 5.16. Initially thought that restarting Tomcat did not succeed, but it just takes a really long time. I am still investigating, but the Activiti deployment was clean, ootb.

Upon shutdown I get things like this in the logs: See activiti-explorer_shutdown-stacktrace.txt

While on startup different things appear to go wrong that may vary per startup. I have (and notice the startup time at the end):  See activiti-explorer_startup-stacktrace1.txt
And on another startup attempt I have:  See activiti-explorer_startup-stacktrace2.txt

I switched the configuration to use MySQL. Before I was still having the default H2 db for testing-purposes only. I do not experience the extremely long startup times now.

Hmmm so must be table locks that somehow interfere. Thanks for the update, Arnold.
