Ack was not sent successfully on try number 1. Read timed out |

with a reboot everything is ok |

It does a HTTP GET request to pull data, then it does a HTTP POST to send the acknowledgement. It might be acknowledging several batches at once, including all the statistics for each batch. It's waiting for a HTTP 200 response from the ack, but the response doesn't return fast enough and it times out waiting. It might help to lower the max_batch_to_send for the sym_channel being used. It shouldn't take very long to update sym_outgoing_batch with status and statistics. But you could check if there is heavy load on that database. It could be the network isn't working right. I've seen read timeouts from VPN connections getting into a bad state or MTU settings on one link of the network causing packet fragmentation. See also https://support.jumpmind.com/kb/article/47-Read-Timed-Out-and-Socket-Timeout . In some cases restarting the VPN or restarting the machine gets networking into a working state. |
