[mosquitto-dev] OpenSSL Error: error:1409F07F:SSL routines:ssl3_write_pe

[Christoph Rotter <cr@xxxxxxxxxxxx>]

Hi all,

 

My versions:

mosquitto c sourcecode (1.4.11)

raspberry pi (Raspbian Jessy)

OpenSSL 1.0.2j  26 Sep 2016

 

 

My target successfully connects via TLS to the broker and publishes messages with qos 2. After a few messages the MQTT connection stops and reconnects:

 

[...]

mqtt_log(16): Client MYTARGET sending PUBLISH (d0, q2, r0, m25, 'test/status', ... (75 bytes))

Publish() mosquitto_publish() FAILED mid 25, rc: 14, errno = 71 (Protocol error)

mqtt_log(16): Client MYTARGET received PUBREC (Mid: 25)

mqtt_log(16): Client MYTARGET sending PUBREL (Mid: 25)

mqtt_log(8): OpenSSL Error: error:1409F07F:SSL routines:ssl3_write_pending:bad write retry

DisconnectClbk()

Start() infinite loop broken (14).

Reconnect() try reconnect

mqtt_log(16): Client MYTARGET sending CONNECT

Reconnect() successfully reconnected

[...]

 

The problem occurs more often on a Raspberry with wifi connection (approx 1 in 10), than on the same target with ethernet cable connection (approx 1 in 60).

 

Any suggestions or tips what I can do or what I can change?

 

Thanks and best regards

Chris
