receiving random grpc._channel._MultiThreadedRendezvous errors from iroha server every 24hours or so
Hello, [I already posted this to the iroha main repo] We are using Iroha 1.2 latest on kubernetes. Setup is a single peer, with a postgresql 13 DB - and under like 20 transactions per second. We are using the python client. We are streaming through the results using a generator. here is the code:
def send_tx_and_stream_result(net, tx, user_private_key):
iroha.IrohaCrypto.sign_transaction(tx, user_private_key)
hex_hash = binascii.hexlify(iroha.IrohaCrypto.hash(tx))
print('Transaction hash = {}, creator = {}'.format(
hex_hash, tx.payload.reduced_payload.creator_account_id))
net.send_tx(tx)
for status in net.tx_status_stream(tx, timeout=args.wlts_iroha_tx_status_timeoout):
txStatusResponse = wallets_pb2.TxStatusResponse()
txStatusResponse.status_name = status[0]
txStatusResponse.status_code = status[1]
txStatusResponse.error_code = status[2]
yield txStatusResponse
Iroha works fine and then, every now and then, we start seeing the message: 'grpc._channel._MultiThreadedRendezvous ' errors and Iroha stops being responsive.

Do you think me using the generator being a problem under heavy load ? Thank you so much, Rafik
The issue is somehow connected with: https://github.com/hyperledger/iroha-python/issues/48
