Frequent crashes

See original GitHub issue

Issue Type:

defect report
enhancement request

Current Behavior:

The dependency track application crashes fairly frequently. In a matter of hours, is what I am observing.

I have attached log output at the end from when the crashing starts. The exception repeats every second until I kill it.

It is not very clear from the log (to me) what the origin of the problem might be.

Steps to Reproduce (if defect):

Let DT run, pushing data to it from Jenkins.

Expected Behavior:

It should keep running 😃

Environment:

Dependency-Track Version: 3.2.1
Distribution: Embedded WAR
BoM Format & Version:
Database Server: H2
Browser:

I run it in a Docker container with 4GB RAM using Oracle 8_181.

I use H2 trying to see it working before I set up a proper DB. There does not appear to be problems with memory or CPU load.

It is not clear to me (from the stack trace) that using H2 should be the root of the problem?!

I guess I will try to set up an external DB to see if it changes anything.
