Dear All,
I've made things a tiny bit better by reducing the log level to 1, so that the rpcd_winreg and rpcd_spoolss files don't grow by several Gb every day, and restarting sernet-samba-ad every couple of hours. People can mostly print after the restart, but quite soon the rpcd_winreg process starts to consume the server and it starts grinding to a halt.
I'm still getting lots of rpcd_winreg processes hanging around consuming resources. I was hoping it was something todo with this:
https://bugzilla.samba.org/show_bug.cgi?id=15201
However, I'm running the latest sernet package 4.17.2.
I'm a bit stuck as to know what to do next...
I've tried building a new print server from scratch on Rocky 9, however that started to exhibit the same rpcd_winreg issue once I'd added a few printers to it, so I stopped as it was going to go the same way.
Any pointers from anyone?.......
Here's my 'top' output after I've restarted sernet-samba-ad, FWIW:
