Dear sge team,

This is my first time installing SGE in my ubuntu. I having problem connection between my sge master and sge client/exec. When using ubuntu 16.04 LTS, connection works well (i can qhost and qsub). But when i upgrade my ubuntu to 18.04 (latest version), i use qhost both client and master error appear as below:

user@sgeclient31:~$ qhost error: commlib error: got select error (Connection refused) error: unable to send message to qmaster using port 6444 on host "sgemaster": got send error

user@sgemaster:~$ qhost error: commlib error: got select error (Connection refused) error: unable to send message to qmaster using port 6444 on host "sgemaster": got send error

My /etc/hosts (as below) is the same when using ubuntu 16.04 LTS 127.0.0.1 localhost 10.89.60.188 sgemaster 10.89.60.185 sgeclient31

I hope you can suggest or guide how to overcome this error? I want to use SGE for my bioinformatics work.

Thank you.

The problem is that the glibc 2.27 slightly changed its internal glob implementation. gridengine uses an internal copy of make, which detects that it doesn't support the new interface and switch to its internal implementation which is slightly broken.

In source/libs/sched/sge_resource_utilization.c:

#if 1

utilization_print(cr, "pe_slots"); printf("this was before utilization_normalize()\n");

#endif

Would be nice to remove this. Spews to the journal when running sge_qmaster via systemd.
