Hi there,
I moved NetXMS from an old server to two new servers. I made the move with the nxdbmgr migrate command and with the help of these instructions. Everything worked successfully, only NetXMS always crashes after some time (approx. 30 - 60 minutes, but sometimes longer). Then I can't log in to NetXMS anymore and I was stuck at Objekte synchronisieren until the timeout.





But if you are already logged in at the time of the crash, you do not get kicked, but stay logged in.

The following error messages can then be seen in the NetXMS log file:


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


Informations about my configuration:

There is a NetXMS server and a database server. In the /etc/netxmsd.conf the database server was entered at DBServer=. Previously (with the old server) the NetXMS server and the database were on the same machine.

Old server:

• Debian GNU/Linux 8 (jessie)
• NetXMS Server Version 2.2.13 Build 9518 (2.2.13)

New server:
NetXMS-Server:

• Ubuntu 18.04.3 LTS
• NetXMS Server Version 3.1.261 Build 3.1-261-ga5f9451ddf

NetXMS configuration file at /etc/netxmsd.conf:

## Logging
# Log file name
LogFile=/var/log/netxmsd

# Increase logging verbosity, 0 (only errors) to 9 (verbose debug)
DebugLevel=7

## Database configuration.
## Uncomment and setup ONE section.

## Option #1 - SQLite (for test installations only):
#DBDriver=sqlite.ddr
#DBName=/var/lib/netxms/netxms.db

## Option #2 - PostgreSQL (recommended):
#DBDriver=pgsql.ddr
#DBServer=127.0.0.1
#DBName=netxms
#DBLogin=netxms
#DBPassword=netxms

## Option #3 - MySQL:
DBDriver=mysql.ddr
DBServer=10.10.11.20
DBName=netxms
DBLogin=******
DBPassword=********************************

## Option #4 - Oracle:
#DBDriver=oracle.ddr
#DBServer=//127.0.0.1:1521/ORCL # Instant Client connection string or SID
#DBLogin=netxms
#DBPassword=netxms

## Option #5 - unixODBC/FreeTDS:
#DBDriver=odbc.ddr
#DBServer=NETXMS_DSN
#DBLogin=netxms
#DBPassword=netxms


MySQL-Server:

• mysql  Ver 14.14 Distrib 5.7.28, for Linux (x86_64) using  EditLine wrapper

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