Okay. Thank you very much!

Okay, thank you very much!  Now it's working.
Can you change this limitation in future releases of NetXMS, because many passwords are longer than 32 symbols. When you see it from security perspective, you shouldn't limt the password length with such a "low" limit. Now 32 symbols are quite "okay", but I think in future this limitation could be critical.

I made a mistake in my previous post. I corrected my old post. This is why your encoded password is different. I installed NetXMS from packages.

Hello,
i want to encrypt my database password with nxencpasswd. At first i executed this command:

# nxencpasswd netxms 'k081vv3C$UKe7z!ysP4Yf408^4m78SGF'
gyuWboDpO52LQYPeHCQ6LlksHezjf3cJmhb5/VpmgJE=


Than i edited my /etc/netxmsd.conf to this:

## Option #3 - MySQL:
DBDriver=mysql.ddr
DBServer=10.10.11.20
DBName=netxms
DBLogin=netxms
DBEncryptedPassword=gyuWboDpO52LQYPeHCQ6LlksHezjf3cJmhb5/VpmgJE=


Now i started netxmsd service and got this error:

2020.01.13 20:57:49.856 Log file opened (rotation policy 2, max size 16777216)

I hope someone knows what the problem is.
Thanks in advance!

What operating system do you use?  Can you connect to your database remotely? You can test it with this command: mysql -u [user] -p -h [ip of db server]

I think you should attach your config files here if someone should help you. 

This shows how my nodes gets deleted:

1. I create a new Node


2. You see the node is there


3. Now I reboot the server
# reboot

4. For a short time the node is still there


5. But after about 1 minute the node disappeares


I attached the log of this test here.

I hope someone knows what the problem is.
Thanks in advance!

Hi Alex,
I posted the requested logs here.
Can we continue this post on this post? This would be great, because the problem mentioned here is the same as here.

Best regards

Hello,
thank you for the update. I think the bug with "Thread "Poll Manager" does not respond to watchdog thread" and  "Thread "Syncer Thread" does not respond to watchdog thread" has been fixed, because there was no error for more than 8 hours uptime now. But the other bug, that rainerh also mentioned here, still exists. Here is a copy of his post:

Hello,
I want do delete 2 (old) Template Groups.
After reboot, the 2 groups are still available.
How can I delete theses groups permanent?

Thank you

I have a new problem and I think the reason is the same like above:
When I create a new node, the new node will work fine until I reboot the NetXMS Server.
After reboot the new created node is deletet.

I attached the netxmsd log file here.
Now I checked db writer queue:

# nxadm -i
netxmsd: show queues

I got this output:

netxmsd: show queues
Data collector                   : 459
DCI cache loader                 : 0

When I execute this command multiple times I noticed that this value goes to approximately 12.000 - 20.000 and than quickly goes down to approx. 1000.

Could you please update packages? 

Hi,
thanks for fixing the bug. I will try it as soon as I get the new patch.

I have found out, that there is a diffrence between a full restart and when I only restart the netxmsd service.
For example when I make some changes and do service netxmsd restart my changes are there.
But when I do reboot my changes are gone.
And some changes are removed after some reboots and that is a very big problem.
When I do # nxdbmgr check after a reboot I get this error: Container 9190 contains non-existing child 79719. Fix it? (Yes/No/All/Skip) yes
Now my saved Nodes are away.

When NetXMS hangs it doesn't save any changes that I make.

In my post before I executed the script while NetXMS did hang. I didn't restart the netxmsd service since the crash I mentioned in my first post. 2019.12.31 12:48:36.346 *E* [                   ] Thread "Poll Manager" does not respond to watchdog thread
2019.12.31 12:48:56.347 *E* [                   ] Thread "Syncer Thread" does not respond to watchdog thread
So NetXMS still hangs.

I don't know if this can help, but I did it:
Now I restarted the netxmsd service and waited for netxms to hang. Than I launched the script. I have attached this file here.
Log file:

2020.01.02 10:16:52.647 *E* [                   ] Thread "Poll Manager" does not respond to watchdog thread
2020.01.02 10:17:12.647 *E* [                   ] Thread "Syncer Thread" does not respond to watchdog thread


I also attached the log file here. As you can see, i lauched the script 3 minutes after NetXMS hangs. Don't be confused about the time in the filename. It's because of the german time shift of one hour.

Yes, NetXMS was installed from packages. I used this guide to install NetXMS. Before I started the script, I installed gdb and all relevant NetXMS packages with these commands:
# apt install netxms-*-dbg
# apt install gdb
And after that:
# ./capture_netxmsd_threads.sh

At the moment I executed the script, NetXMS hangs.
In /tmp I found netxmsd-threads.21769.20200101-212952. I attached this file here.
