Hi.
We are using that ltp.sh file

And very strange, that we pass ltp part, and job is stuck after echo 1 command

In normal situation 

-ltp results
+ echo 1
+ ret_val=1
+ exec
+ return 1

​in our

-ltp results
+ echo 1 

And lava doesnt run any commands, just stuck until timeout

That it the question. What it could be?

I'm not sure what you mean by that. In the test definition we use it's
ltp.sh is called in the foreground:
https://github.com/Linaro/test-definitions/blob/master/automated/linux/ltp/ltp.yaml#L51
It will print all output from LTP as it comes. Example here:
