I prepared some time ago Docker Container Image based on CentOS 7.9 with erlang-otp build 22.3.4.11 from sources - https://github.com/erlang/otp/releases/download/OTP-22.3.4.11/otp_src-22.3.4.11.tar.gz. All worked fine - as expected:

Erlang/OTP 22 [erts-10.7.2.4] [source] [64-bit] [smp:32:32] [ds:32:32:10] [async-threads:1] [hipe]

Eshell V10.7.2.4  (abort with ^G)
1> gen_sctp:open().
{ok,#Port<0.6>}
2>

Now I'm trying to do the same but on Rocky Linux 8.4/8.5 Docker Image and build the same version - 22.3.4.11 from sources. All were successfully compiled on the same server (as CentOS 7.x based Docker Image) but sctp does not work correctly for Rocky Linux Docker based Image only.

Erlang/OTP 22 [erts-10.7.2.4] [source] [64-bit] [smp:32:32] [ds:32:32:10] [async-threads:1] [hipe]

Eshell V10.7.2.4  (abort with ^G)
1> gen_sctp:open().
** exception error: bad argument
     in function  gen_sctp:open/1
        called as gen_sctp:open([])
2>

I trying to test also 22.3.4.23 version and the same error were shown.
I also tried install from Rocky RPM packages yum install erlang.x86_64 - 22.0.7-1.el8 and all working fine.
I would to use own compiled version on Rocky to have easy way to update erlang to newer version.

Please let me know what should I do to fix exception error: bad argument for gen_sctp:open(). for Rocky Linux?

  • If you run `netstat -s`, does it show an SCTP section? If not, does `modprobe sctp` fix it? – legoscia Nov 17 '21 at 09:27

    `netstat -s` showing SCTP section for CentOS docker image run and RockyLinux too. sctp module is loaded by default in host system `lsmod |grep sctp`. – Diodak Nov 17 '21 at 09:33

I've tested everything again for kernel 4.19.x and 5.15.5 and notice below things:

  1. Red Hat 7.x machine running on kernel 4.19.x:
  • CentOS 7.9 based Docker Image with erlang-otp build 22.3.4.11 from sources - work correctly ({ok,#Port<0.6>})
  • Rocky Linux 8.5 based Docker Image with erlang-otp build 22.3.4.11 from sources - does not work (** exception error: bad argument)
  1. The same Red Hat 7.x machine but running on kernel 5.15.5:
  • CentOS 7.9 based Docker Image with erlang-otp build 22.3.4.11 from sources - work correctly ({ok,#Port<0.6>})
  • Rocky Linux 8.5 based Docker Image with erlang-otp build 22.3.4.11 from sources - work correctly ({ok,#Port<0.6>})

It looks that Docker Image created based on Rocky Linux 8.5 likes modern kernels. Older 4.19.x kernel cause issue but newer 5.15.5 kernel works as expected with the same Rocky Linux 8.5 based Docker Image - I don't know why it fixes problem.

BTW. Default Rocky Linux 8.5 kernel is 4.18.0.
