vCenter 7: Catalina Logs filing up, tomcat-users.xml missing?

We were receiving errors on our vCenter servers that the log disk is getting low on disk space. According to VMWare KBs we checked what is consuming space. We found espiecially a lot of log files named “catalina_(DATE).log” with 11mb size, going back almost a year.

I checked the content of the log, and every 10 minutes it creates the same error message:

2021-04-12T23:59:53.056Z WARN org.apache.catalina.users.MemoryUserDatabase Failed to close (conf/tomcat-users.xml) /usr/lib/vmware-sso/vmware-sts/conf/tomcat-users.xml (No such file or directory)
    at Method)

    at org.apache.catalina.core.ContainerBase.backgroundProcess(
    at org.apache.catalina.core.ContainerBase$ContainerBackgroundProcessor.processChildren(
    at org.apache.catalina.core.ContainerBase$

Veeam simply tells me to delete the files and to enlarge my log disk, which I did. But it still bugged me what is going on, and so far I did not find anthing in the web related to vCenter.

Anyone has an idea what is going on here, and how to resolve this error? I know that there are many ways to ignore it, and maybe it is safe to ignore it, but I only want to know if the error itself can be fixed.

xcode – Installing cocoapods to macOS Catalina

In my mac mini I’ve running Catalina 10.15.7. I’ve also installed Xcode 12.4. Now as I’m using third party library I’m trying to install cocoapods in my mac.
So I used this –

sudo gem install cocoapods

which I got from official website.

But I’m getting this –

I’ve seen this question but my ruby version is –

ruby 2.6.3p62 (2019-04-16 revision 67580) (universal.x86_64-darwin19)

I’ve also take a look in this but could not able to solve the problem.

I’ve used this –

xcode-select --install

but got –
xcode-select: error: command line tools are already installed, use “Software Update” to install updates

So, Is there any ruby dependency I’ve to install first or I just missed something?

printing – “Add printer” (from network) fails silently (Catalina 10.15.7 (19H2))

When going through the usual steps, my network printer shows up via Bonjour Sharing, but when I double click it and it shows a progress bar, it completes but the list is still empty.

It’s an HP office jet 3830. What’s strange is when I add the device’s “Fax” driver, it works fine. Just the printer doesn’t work.

What could be wrong?

(it looks like the same issue as this which no one responded to: Install remote printer fails)

pc – Is there a PowerPC emulator for Catalina?

Mid-2012 MacBook Pro. Currently running SheepShaver 2.4 to enable using an old, old (1990) double entry accounting program called Business Sense 2.3. I’ve never found anything that comes close to its simplicity and ease of use; but I’m stuck in High Sierra because there seems to be no emulator that runs in anything higher. Also still occasionally use Adobe Creative Suite CS6, which I purchased, and really don’t want to pay for a subscription based version. So, an additional question would be is there a 32-bit emulator for Catalina.

terminal – macOS Catalina does not allow incoming connections from local network. Firewall is down

I starting facing this issue some days ago. Even when the firewall is down, I can’t reach my mac from my local network. Ping is not responding neither. Some test I’ve done:

From my console

nrossi@~$ netstat -an | grep 8080

Firewall is disabled. (State = 0)

Any help ?

Certain apps on Mac OS Big Sur crash after upgrading from Catalina

After upgrading from Mac OS 10.15.x (Catalina), certain apps and audio plugins suddenly started crashing with memory allocation errors. Reinstalling the OS did nothing and my searches on the Internet didn’t seem to bring up anything useful. These crashes do not occur on other machines running Big Sur, only this particular one.
Below is a snippet of the log which shows the crashing thread. Interestingly enough, in all of the crashlogs, the libsystem_malloc.dylib, libsystem_c.dylib, libsystem_pthread.dylib, are mentioned.
I am at a loss what to do and where to look next.
Thanks for any help!
