Repeated frame-drops due to client attempting to catch up to server

[nldw]

In a match earlier today (ID 4587369) I found the game freezing usually every minute, but sometimes as often as every 10-20 seconds, even while doing things like purchasing items in spawn, or walking around trying to test it.

After opening the console, I found that the game is consistently outputting this error:

[Client] Current tick is 129610, but we have received a message for tick 129618. Processing all messages up to 129618 now.
[Client] Last server executed command is 128789 on tick 129618. Duplicating command 128786 3x to catch up. New outgoing command is 128789
[Client] Slamming client tick to server tick. abs( server tick 129618 - client tick 129604 = 14 ) > ( cl_clockdrift_max_ticks 3 + sim ticks 6 = 9 )
Excessive frame time of 150.51ms clamped. Acting as if the frame only took 100.00ms. (Last amnesty was 'ConsoleVisible', 3.67s ago)
127.86ms Frame Boundary

I have absolutely no clue what might be causing this - it has happened again in 1-2 other matches but my end-of-game ping stats show no issue on my end, and even if so, I don't see why a network error would be causing my FPS to tank?
