Hi,

I probably found the bug. Try to patch src/server/tools/nxdbmgr/upgrade.cpp as following:

Find line 492 - it should be

TCHAR *config = DBGetField(hResult, i, 3, NULL, 0);

insert after it the following code:

if (config == NULL)
config = _tcsdup(_T(""));

Rebuild nxdbmgr - it should work.

Best regards,
Victor

It seems that this is related to the maps. I am not fully using my maps at the moment. Could I remove the maps from mysql tables? If so, what would the proper sql commands to get rid of the maps?

Exactly the same issue under FreeBSD (FreeBSD 9.3-RELEASE, mysql-server 5.5.39).

Indeed, FreeBSD port of NetXMS is broken now: it does not install shared libraries files required for both netxmsd and nxagent (i.e., libnxsqlite.so.1.0.0,libnxdb.so.1.0.0 and so on) .
