Binary generated from jenkins pipeline throwing error in linux box while running - netpoll failed

[nova...@gmail.com]

I used 1.12.6 Go library to develop GoLang Application with Beego framework. When I generate Binary in Linux box and run that binary in same linux box, its run fine.

Issue is: when I generate Binary in Jenkins Pipeline, and run that binary in Linux box, it gives error, epollwait on fd 4, and netpoll failed.

I used similar build script in Linux as well as in pipeline.

Can someone please guide me on this issue.

Please show us the exact error output. Thanks.

runtime: epollwait on fd 4 failed with 38
Fatal error: runtime : netpoll failed

runtime stack:
Runtime.throw(0xa59c24, 0x17)
/apps/jenkins/build/tools/go1.12.6.linux-amd64/src/runtime/panic.go:617
.....

This generates when I run generated binary from jenkins pipeline, in linux box using "nohup ./binary"

But, when I generate binary in same linux box, and run, it run fine without any error.

Thanks. Errno 38 is ENOSYS. This seems to mean that the kernel where
the program is running does not support the system call epoll_pwait.
The epoll_pwait system call was added in Linux kernel version 2.6.19.
What kernel version are you running the program on?

Binary generated in Linux 3.10.0

And Running in 2.6.18

What was the Linux distro and kernel version of the system on which you attempted to run the binary?

Go requires Linux 2.6.23 or later.

Yes, and more generally RHEL 5 is not supported and known to fail.
This is mentioned at https://golang.org/doc/install .

Sorry. But note that as far as I know RHEL 5 is end-of-life in a few
months. And RHEL 6 has been available for over nine years.
