I recently installed 0.2.23.  I previously had 0.2.22 installed, but instead of an upgrade I did a clean install (deleted DB, deleted old install directory, did fresh configure/make/make install in 0.2.23 source directory).

The problem I am having is that nodes disappear after NetXMS restart.

After a little bit of investigation, it seems that nothing ever gets written to the NODES table.  Even after I add nodes via the console app, the NODES table remains empty.  The other tables seem to survive the restart (actions, event log, etc.).

I ran NXDBMGR and this was the result:

Configuration file OK

Looking in the server log, I see a lot of failed queries such as:

So it's like the initial data structure isn't getting created correctly.  Short of completely wiping the box, I have started from scratch twice with the same results.  Here is my configure line:

./configure --prefix=/opt/netxms --with-server --with-mysql --with-agent --with-openssl --with-nxhttpd

I am using MySQL 5 on Ubuntu 8.04 server.  Please let me know if there is anything else I can post regarding this issue.

Thanks!
