NetXMS Support Forum

Hello Victor,

Regarding this issue :
"connection refused logon to NetXMS Cons after upgrade NetXMS 2.0 to NetXMS 2.0.2" (netxms core crash on startup)

In this reply post I attached the files .info and .mdmp you requested.

Kind regards,

Mark (MarkusO)

Yesterday i successfully upgraded to 2.0.2 at around 14:00h.

Unfortunately this issue, "daily server crash - Thread "Item Poller" does not respond to watchdog thread", occurred again 5 hours after the successful upgrade to version 2.0.2.

* application and services still running, but no dci polling values
* Error viewing last values for each node, screenshot attached in this post.
* empty dashboard graphs

Any advice in fixing  this issue is more than welcome.

Solved this issue by :


- removing all NetXMS installations (but keep the already existing MySQL database)
- moving the whole (content of)  C:\NetXMS folder to an .old folder
- installing netxms-2.0.2-x64.exe to a new folder c:\NetXMS
<no errors occurred>
- running c:\NetXMS\nxdbmgr -upgrade

Everything working OK now in new NetXMS version 2.0.2 with the existing database.

On a test server i am upgrading from 2.0 RC2 to 2.0.2.
At the end of the 2.0.2 installation an error occurs : "service named netxmscore already exist" -->see attached screenshot


Server OS : Windows 2008 Server R2 SP1
Database : MySQL


Followed upgrade instructions as below ( NetXMS Server Installation Guide ):
1. Download the latest version from https://www.netxms.org/download, if you don't have it. You will need Windows installer (named netxms-VERSION.exe, for example netxms-1.2.15.exe).
2. Stop NetXMS server.
3. Check database for possible inconsistencies:
C:\NetXMS\bin> nxdbmgr check
Proceed to the next step only if database checker does not report any errors!
4. Run NetXMS installer and follow the prompts. Normally, you will not need to change any settings on installation wizard windows.


Any suggestions for resolving this issue?
Thanks in advance.

Kind regards,
Markus

Attached in this post a better more readable debug output logfile. (output of command: netxmsd -D 9   command line Windows )

Ok thanks for the advice and support.

I will upgrade to version 2.0.2 and then further evaluate if this issue is resolved.

Again thanks for your help.

With your help (no re-intialize) I now successfully have installed NetXMS 2.0.2. 

Unfortunately when i now login to the NetXMS console i still get the error "connection refused", as like before.

When i checked if the server is actually running i noticed it wasn't.

Troubleshooting from there :
- started netxms core service from Windows GUI --> error "can not start the NetXMS core service on the local machine / Error 1067 the process has unexpectedly terminated ", screenshot with error message in dutch attached in this reply

- started netxmsd from Windows command line --> error "Error 1067 the process has unexpectedly terminated" screenshot with error message in dutch attached in this reply.
Also screenshot of application error in event viewer attached in this reply.

- started netxmsd with debug -D 9 --> debug output file attached in this reply



Any ideas for following steps to take in solving this issue?

Thanks in advance.

Kindest regards.

Situation:
In a test environment i run NetXMS version 2.0RC2.

netxmsd: sh sta
Total number of objects:     489
Number of monitored nodes:   68
Number of collectable DCIs:  272

4 dashboards have been configured and are up and running. During most of the day everything is working properly. DCI values are polled and displayed nicely.

Issue:
On an average of once a day the server seems to crash. In the Windows event viewer the error : Thread "Item Poller" does not respond to watchdog thread.

From that moment the dashboards are empty and show an error message. At the same time when I execute 'last values' an error message is shown and no values can be displayed. See attached screenshots.

When i view the Windows services it appears that netxms core service is still running. But when troubleshooting this issue the only solution to temporarily solve the issue is stopping and starting the NetXMS core service. Eventually resulting with no history in the dashboard graphs.


Any suggestions in fully solving this issue?

Thanks in advance.
Kindest regards.

the screenshot

I tried starting netxmsd, Unfortunately without any success.

Eventually I decided to remove the installation from the testmachine (and keep the already existing database) and then to install and run setup again.

At the end of the installation/setup, at 'applying server configuration', an error message is displayed :

error:sql query failed, CREATE  TABLE metadata.....<see attached screenshot>

I can not continue and complete setup after the error.

Any suggestions for next steps and further troubleshooting? I still want to try to use the existing database that i already used with version 2.0

Thanks in advance.
Kindest regards.

Before upgrading on the operational network i first upgraded my testmachine with NetXMS 2.0 to the newest release NetXMS 2.0.2

Since then I am not able to logon again to the NetXMS Console. -->error message : connection refused

On the test machine the NetXMS database runs on a SQL Server 2012 (SQLEXPRESS) instance.

troubleshooting until now :

-ran command line : nxdbmgr upgrade
this reported a successful upgrade
new login attempt -->connection still refused

-ran command line : nxdbmgr check
this reported a database lock, and removed the lock
new login attempt -->connection still refused

-ran command line : nxdbmgr resetadmin
this reported a successful reset of the admin account to the default password "netxms"
new login attempt with default admin credentials-->connection still refused


Before i upgrade the live operation to 2.0.2 i want to sort out this issue.
So hereby a request for help.
Any suggestions?

Kindest regards,
Mark
