Troubleshooting

Manager stops periodically

I see the following message in the Manager log file:

[FATAL ][PID] Flopsar cannot run any longer. No license control file found. Shutdown initiated.

Manager creates a license lock file in /tmp directory. If this file is deleted, then Manager stops. It occurs on Red Hat-like distributions usually. In order to prevent the operating system from deleting this file, you can create a file /usr/lib/tmpfiles.d/flopsar.conf with the following contents:

x /tmp/*.flp

Please, refer to tmpfiles.d(5) man page for details.

I see DROPPED in the Parameters column in Workstation

This means that instrumented JVM drops parameters due to memory pressure. Either, increase memory limits for your application or decrease instrumentation.
