pmd high CPU usage

For a couple of days my laptop has been consuming a lot more power than before, noticeable by how fast the battery runs out when not plugged. This is matched by periodic (~20-30s) fan noise spikes typical of high CPU usage. This happens even when I close all applications. I've installed atop to try and find out which process is causing this:

    PID     TID S  CPU COMMAND-LINE (horizontal scroll with <- and -> keys)                                                              1/65
 351173       - E  50% pmd
 350924       - E  50% pmd
 350675       - E  11% /opt/traps/bin/pmd
 152048       - S   3% /snap/firefox/2277/usr/lib/firefox/firefox -contentproc -childID 6 -isForBrowser -prefsLen 33176 -prefMapSize 244985 -

Varying slightly over time, always with pmd on top. What does this mean? What's pmd? How can I solve it?

I think that the problems started after the latest software upgrades that I installed. I have Ubuntu 20.04.5 LTS.

'which pmd' might give you the process location. 'lsof | grep pmd' might give you disk activity 'pmd --help' or 'man pmd' or 'sudo renice -n 20 $(pidof pmd)' might tame it a bit. or chase up the parent process if any https://www.serverlab.ca/tutorials/linux/administration-linux/how-to-find-the-parent-process-id-with-bash/

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
