[ocf/udp/tcp/ws] Server on Arduino101 over ENC28J60 will hang after long-running

[qiaojingx]

Description

OcfServer, UDPServer,TCPServer and WebSocketServer all hang after long-running on Arduino101 with ENC28J60 Ethernet Board.

Test Code

WebSocketServer.js;
TCPEchoServ6.js;
TCPClient6.js;
UDPEchoServ4.js;
OcfServer.js;

Steps to Reproduction

1. connect ENC28J60 to Arduino101 by wiring the below pins on boards.

CS  -> IO10
SI -> IO11
SO -> IO12
SCK -> IO13
VCC -> 3.3v
GND -> GND
INT -> IO4

2. Connect ENC28J60 Ethernet Board to PC via Ethernet cable.
3. Flash Arduino101 with test sample.

$ make JS=samples/UDPEchoServ4.js FORCE=zjs_net_l2_enc28j60.json
$ make dfu

4. add router and address to PC

ip route add 192.0.2.0/24 dev eno1
ip addr add 192.0.2.2 dev eno1

5. Connect UDPEchoServ4.js using python client:
   python test-udp4-client.py

Actual Result

1. OcfServer.js
   OcfServer hangs and OcfClient got error [FATAL]:10, cannot reconnect again.
   

2. WebSocketServer.js
   WebSocketServer hangs, cannot receive data from node client, cannot reconnect with node client again.
   

3. TCPEchoServ6.js
   TCPServer6 got error "malloc failed" first, then hangs. cannot receive data from python client, cannot reconnect with python client again.
   

4. UDPEchoServ4.js
   UDPServer4 hangs, cannot receive data from python client, cannot reconnect with python client again.
   

Expected Result

Server should always works fine.

Test Builds

Branch	Commit Id	Target Device	Test Date	Result
master	b32969f	Arduino 101	Dec 28, 2017	Fail

I re-test this issue and get another issue that looks like #1737 with ENC28J60 Ethernet Board.

See my comment on #1737, I think we have a leak somewhere, because it was failing on malloc

[grgustaf]

As @jimmy-huang suggested in IRC, it seems like this may have been fixed by #1816 as well.

[jimmy-huang]

@cuiyanx please re-test with #1816

[cuiyanx]

I re-test this issue with PR #1816, this issue is fixed and not reproduced. So closed.
