Used our stage fuzzer and synced chiado with nimbus.

After each restart I was getting warning:
Timeout on waiting for active tasks for feed HeadersSyncFeed 1

After one of restart on already synced node (on tip of chain) it thrown an:

System.OverflowException: Underflow in subtraction 0 - 340282366920938463463374607431768211454

From this moment it was not syncing any Headers but it still had some to download and - also because of that my node is unable to download bodies and receipts.
