I have my own node setup using parity for ethereum. Everything was going perfect. But from today , means right after Ethereum hard forked into their improved version of "Istanbul" at block 9069000 last night, sometimes my send Txn function return hash that is not available on any explorer.
like this: 0x226e05043929fbc9968485761cd69203f3b751d700f9fb1598a954abefb35337
And many other txns hashes returned by function but these are not found on any explorer. I guess these txns are not going to be add in memPool..
What community suggest?
