bsc full nodes often lags behind the network. it's freezes and then starts to catch up. both nodes are running on nvme.

what the problem looks like: the node stops syncing while the network height grows, then the node starts to catch up with the network enter image description here

node1 config:

DatabaseCache = 8192
MaxPeers = 150
--cache 20480 
--syncmode full

node2 config:

DatabaseCache = 8192
MaxPeers = 200
--cache 20480 
--syncmode fast

log before problem:

T05:54:02+0000 lvl=info msg="Unindexed transactions"
