Experimental: false

Docker host is redhat7.4 with 72 cpus and 250GB mem

I am doing a variety of things inside container (calling make, etc)
I am seeing resources issues in which i dont see outside of the container on the same host

I dont know if it’s Docker issues or some config centos6.8 issues. any ideas?

Issues im seeing are:
• make[1]: vfork: Resource temporarily unavailable
• clang-5.0: error: unable to execute command: posix_spawn failed: Resource temporarily unavailable
• +++ fork() failed:
• Cannot create GC thread. Out of system resources.
Error occurred during initialization of VM
java.lang.OutOfMemoryError: unable to create new native thread

I am running “docker run” with
"–privileged "
"–cap-add=SYS_PTRACE "
"–cap-add=SYS_ADMIN "
"–cap-add=SYS_NICE " \

I thought it was maxproc thing so i’ve changed /etc/security/limits.d/90-nproc.conf to (it was originally 1024, but this didnt help either)

  •      soft    nproc     10240
    

root soft nproc unlimited
