Dear all,

        We are encountered with an issue that our job always exits halfway when running  a  long duration test case (around 20 minutes) which outputs nothing , and lava server reports an InfrastructureError error and prints as below :

Connection closed by foreign host.Marking unfinished test run as failed

definition: lava
result: fail
case: 0_apache-servers1
uuid: 597_1.4.2.4.1
duration: 603.53
lava_test_shell connection dropped.end: 3.1 lava-test-shell (duration 00:10:05) [ns_s1]

namespace: ns_s1
extra: ...
definition: lava
level: 3.1
result: fail
case: lava-test-shell
duration: 604.55
lava-test-retry failed: 1 of 1 attempts. 'lava_test_shell connection dropped.'lava_test_shell connection dropped.




And we just test it with a very simple python script as below:

#!/usr/bin/env python3
import time
print('Hello,world!')
time.sleep(1200)
print("Hello,Lava!")


We can see 'Hello,world!' string outputs , but there's no more output of this program found on webUI!


We just don't know what's wrong , so we have to mail to you for help!

Sincerely,

    Chuan Su
