Unable to remove reporter and storage

[chelun-c000]

I have been troubled by this issue for a long time and would appreciate it if you could help me determine whether there are any issues with my operations. Thank you! :) (I use Ubuntu 23.)

I sequentially entered the following commands in the control panel:

add storage Prov output=/tmp/provenance.ttl audit=http://spade.csl.sri.com/rdf/audit.rdfs
add filter OPM2Prov position=1
add reporter Audit

All results were displayed as successful. I then performed various actions on the computer (compiling C language files, git clone, push, etc.) to generate some audit logs. After completing these operations, I entered remove storage Prov (or remove reporter Audit) in the control panel. At this point, SPADE became unresponsive. I subsequently exited and attempted to stop SPADE. However, upon checking the spade status, I discovered that SPADE's status remained as "running."

I have tried this process numerous times before and noticed that whenever I use the remove storage Prov command, there is no response, leading to subsequent issues. I would like to inquire if there might be a problem with the order of my operations.

Additionally, I would like to know why there have been no records generated in the /tmp/provenance file. Could you please help identify the possible reasons for this issue?

Here is the log when I entered remove reporter Audit, and SPADE became unresponsive:

The issue is with the filter.
