InvalidOperationException when stopping Gnosis chain during sync

[kamilchodola]

During very initial phase of sync I stopped gracefully a node and got this exception:

System.InvalidOperationException: Cannot access a closed file. Trying to write bloom index for block 38248384 at bucket 9337

It is not breaking anything in terms of syncing progress but need to verify if headers sync properly downloaded and saved all the data
