Hi, I have some strange problems here with a AMD box in intel compat mode.
An upgrade to 5.3 RC1 did not help at all and still shows the problems.
Working box, same kernel and userland as mx3:

Why rbldnsd shows up as a kernel process ? And there are even other procs
showing up as kernel procs with missing cmdline ...

clamav 1798 0.0 1.8 37592 37008 ?? I 7:00PM 0:00.00 [mimedefang-multiple]
All cmdline args are gone. Any thoughts ?
