Current behaviour

bitcoind doesn't progress with synchronization despite approx. 4 months lag, doesn't consume much CPU or RAM, uses disk IO, produces large amount of logs like e.g. [leveldb] Generated table #3982690@4: 31588 keys, 2162389 bytes for hours (there was a test for more than 8 hours).

Reproduced 3 times out of 3 tests (one with a pre-built version 27).

Expected behaviour

bitcoind finishes synchronization in an hour or so.

Steps to reproduce

Preconditions:

1. Bitcoin 28.1
2. Pruned node (550MB)

Steps:

1. Launch bitcoind
   bitcoind -datadir=/mnt/sd/Bitcoin_data -daemon=0 -debug=all -blocksonly=1 -debuglogfile=/tmp/debug.log -prune=550 -dbcache=2048

Relevant log output
