Re: RIM Node is down but services are running

  1. Open regedit
  2. Navigate to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services\Tcpip\Parameters
  3. Either:
    1. Edit the existing MaxUserPort entry to a higher value. The default value is 5,000 and the maximum value is 65,534.
    2. Create a DWORD Entry, edit the entry, and enter a decimal value

Hope that helps.

Re: RIM Node is down but services are running

Levi,

Thanks for reply.

I am not 100% sure that this was a resource issue...

In the case Rohit has mentioned, the full system restart has fixed the problem and all nodes are available now.


I did a single node restart first (the one that was offline), but it did not help.

Full system restart (all 7 nodes) have fixed the issue.


My main concern is how to detect this problem in the future.

We are running a services status check on all nodes and it sends the alert if the critical service is down.

In this case all services were running and I did not notice that we have a problem until I've looked at QMC over the weekend.

Apparently, the disconnect happened on Friday...

Any suggestions how we can detect this kind of issues in the future?

Regards,

Vlad

Re: RIM Node is down but services are running

Do Memory in primary partition less than 8 GB can be any cause?

Re: RIM Node is down but services are running

We have ENOUGH memory on that server.

We do have ~6 GB of HD free space on C: partition, but it should be enough also... Considering that all apps / logs are located on D: partition.

Both QMC and Hub are not reachable.

Using pgAdmin seems that PostgreSQL database is not responding.

What does could be the root cause of this error ?

Thanks in advance for your time.

Re: RIM Node is down but services are running

I'm facing a similar issue since I upgraded to April '18 version.

Thanks

Re: RIM Node is down but services are running

I would strongly recommend to NOT use the April 2018 release.

It's very unstable and it's not worth to spend time handling issues there.

The June 2018 SR1 release is better, but there are few issues there as well.

We are still on Feb 2018 version.....
