Hi Victor,

Did you check whether the port 31001 is not in use already ?

NiPConnect2: 172.18.50.120:31001

Pls check with the help of LSOF or NETSTAT command to see if it is associated with any other service, then you can associate a different port for it and then try, do all this with Root user. Also maintain the Host entry (/etc/hosts).

Hello Sujit,

The port and host is in /etc/hosts and continue the problem.

Hi Victor,

Were you able to find a solution to this problem?

We are having a similar issue, for us the TREX system is down every 11 days.

Hello Tanmeya,

The problem is network revise the etc/host and etc/services.

Hi Victor,

Thanks for your reply.

In our scenario, I think "SAP Note# 1499868 - TREX 7.00_7.10- Shared memory lock was deleted" will help.

Best Regards,

Tanmeya
