XProtectRemediatorSheepSwap using ridiculous amount of memory

Over the last couple days, my computer has periodically ground to a halt. The culprit appears to be XProtectRemediatorSheepSwap – which uses anywhere between 30 to 40 GB of memory! (I only have 16GB, so it's clearly using lots of swap). The only thing that helps is rebooting, but even that's only proved temporarily effective so far, as it begins to happen again after some usage.

The other thing I noticed is that it's spamming my console with thousands of these logs:

default 05:24:09.614543-0800 XProtectRemediatorSheepSwap [0x7fb5e20c8de0] activating connection: mach=true listener=false peer=false name=com.apple.bird

default 05:24:09.614682-0800 XProtectRemediatorSheepSwap [0x7fb5e20c8de0] failed to do a bootstrap look-up: xpc_error=[3: No such process]

default 05:24:09.614711-0800 XProtectRemediatorSheepSwap [0x7fb5e20c8de0] invalidated after a failed init

error 05:24:09.614851-0800 XProtectRemediatorSheepSwap Error querying cloud docs root URL: <private>

what's going on? is there anything I can do? I'd really rather not have to lose a day to a clean install.

p.s. I don't seem to be able to change the tags on this, but it got tagged incorrectly – I am indeed on macOS 14.3, not 11.3...

I'm disappointed that I wasn't able to figure out what specifically was causing XProtect to go haywire, as I'll admit there was a lot of cruft on my computer – but nothing *new* really stood out as the cause of the issue, that started happening all of a sudden.

But I finally broke down and did the clean reinstall, just keeping the user directory, that I'd been dreading for a while. Took me the whole weekend, and I was actually worried that the computer would run out of memory / disk space while I was doing the final Time Machine backup, but it somehow made it through. Back to work today, and everything seems good!

I had the problem with 12.7.3, almost every day, but it hasn't happened for the last week or so. I've got security updates set to install automatically, so maybe Apple have pushed something out to fix it?

Since the last release I have seen several computers suddenly running out of application memory. Whatever XProtectRemediatorSheepSwap is, it seems to have a bad memory leak.

I followed dbolli's advice to disable "Install Security Responses and system files" in the Software Update settings, but XProtect continues to run itself even after rebooting. I then booted into Recovery Mode and did "csrutil disable", then rebooted, but XProtect still runs itself. Am I missing something here, or is it actually impossible to turn this service off...?

Quick update....still happening every day. Most of the time I just exit Firefox, etc. and leave it to sort itself out. On 2 occasions (including just now) I couldn't do anything and eventually the Mac rebooted itself. I've sent Apple the reports.

I've got a 4GB Mac mini running Monterey 12.7.3 and XProtectRemediatorSheepSwap is currently bogging it down with 6.2GB memory usage according to Activity Monitor.
