The machine is working fine (load still 2.46 just like befor applying

Thanks. I'm a bit surprised at this, so I would appreciate knowing if
your load remains normal after another day or more of running this
code.
Thank you.

And if you're feeling even more adventurous, might I ask you to revert
these changes and try the original patch again to be double sure it
kills the machine? It's just that this second version shouldn't be
that different than the first

It may be possible that it's just one particular action or email message content that triggers a problem with this patch - in which case maybe SM gets caught in an endless loop eating all your server memory or the likes.
