Hey, guys. I have new info.
TL;DR Those repeated "Installing the package" messages you see in that cfpm-audit.log are nothing at all to be concerned about. They do occur on EVERY CF restart.
Details:
First, I missed that you were referring to the cfpm-audit.log. I thought you were talking about the coldfusion-out.log. As you all may know, that log also tracks information about package processing. And as I mentioned above, I've been helping people to understand that when a CF update entails package updated, those package updates (uninstalling the old/installing the new) happen during the next start AFTER the cf update, and that's tracked in the coldfusion-out.log.
That's why I had said that if you saw that happening again and again on CF restarts, it would suggest that the package updates were failing for some reason. I've definitely seen that below (and in fact with the latest updates last week to CF2021 and 2023--but that's not the issue Dordrecht is raising here.)
I did some more digging into things this weekend (especially because of that other issue), and separate from that I can confirm that indeed the lines dordrecht reported above do appear in that cfpm-audit.log on EACH CF start ("Installing the package", "Deploying bundle", as well as "ServiceRegistration for package"). I'd never really noticed that before. There are several such lines per package, and by default there about 50 packages, so there are literally a few hundred lines of this sort on each restart--and I have confirmed it's been like this since the very first install of CF2021 which again introduced the whole package management feature. (I found it in the cfpm-audit logs I still have from the very first day CF2021 was release in Nov 2020.)
So Dordrecht, I understand how it was odd-looking to find those lines in that file, but again it's perfectly normal. As for why it says over and over like that (on each restart) that it's "installing" the jar files related to the package, I can only surmise that it's just got something to do with how the OSGI-based package management mechanism works. (This is perhaps what BKBK had in mind when he regarded the process as "private" and "information-hiding". I can understand his contention now. Again, when I disagreed I was referring to when I thought you were referring to log lines in the coldfusion-out.log instead. If one saw uninstalling of packages there, that WOULD be a problem--and again when I was writing that I had started to observe the problem that started with the latest updates of last week.)
Finally, I have confirmed also that there's NO change to the files referred to in those log lines. Further, I've confirmed that there's not even a change in the cfusion/bin/felix-cache folder where the packages really are "deployed to". Those files only change when there IS an actual update to the packages. Again, I've dug into all this this weekend on multiple machines.
But perhaps Adobe or someone else may have more to share about all this. But in the meantime it may help not only you all but anyone who may come looking for info on this issue, these messages, etc.
