It's probably firewalld service running on qmaster. Try to stop it or add exception Otherwise GE has no problem running on Centos 7.

I appreciate that that is not officially supported, but it is what I have to work with. I can build SGE from source just fine, either by rebuilding the source rpm or the distribution tarball. Installing these to /opt/sge also works without issue. However running one of the install scripts (inst_sge, start_gui_installer) invariable fails when it attempts to launch qmaster: > Starting Grid Engine qmaster > sge_qmaster start problem > sge_qmaster didn't start! > sge_qmaster start problem On further investigation it seems that the qmaster process is indeed running, but communication with it is not possible. Indeed, running qstat yields: > error: commlib error: got select error (Broken pipe) > error: unable to contact qmaster using port 6444 on host "radium" According to `ps aux | grep qmaster`, the process /opt/sge/bin/lx-amd64/sge_qmaster is running however. This issue occurs on 8.1.9 as well as on 8.1.8. I tried installing 8.1.9 on centos 6 and it works as expected there. I should mention that all of this is happening inside a qemu VM on a Slackware host. For completeness it is launched as follows: qemu-system-x86_64 -drive file=sda_sge.cow,format=qcow2 -m 1G -enable-kvm -smp 2 Any help/advice is greatly appreciated.
