Is this the full error/warning message?

[FabioLuporini]

is this still an issue? can we actually ignore it now?

From @george Iordanescu's on SLack:

• When runing the benchmark in a docker container, I get "mbind: Operation not permitted" waring. Running the container with --security-opt seccomp=unconfined fixes this, but it looks to me like using a sledgehammer to open a walnut (or whatever the English lang correspondent that is). Any guidance on this?

[keithyzk]

same issue here.
security_opt is not working on docker swarm.The mysql log is full of information like this.

Hi Keith, it has been a long time since we last time tried this. Are you trying to run Devito on Azure?

Hi , George. we are not running on Azure. We have similar problems on both physical and virtual machines.
Thanks Reply.

Uh, I have to see this long time. Can you give as some more context? Like what machines, compilers, mpi version etc?

[keithyzk]

呃，我必须看到这么长时间。你能提供更多的背景吗？比如什么机器，编译器，mpi版本等？

dockerfile is similar to this(It's just that the mysql version is different, I use v8.0.17)

Can you reproduce with this issue with no devito code? i.e. just an mpi ping-pong?
