Quote from: Filipp Sudanov on November 19, 2025, 06:58:24 PMYes, messages aboutExactly. I'll try to check via Process Manager the thread stack - if/when it hangs up again.
Thread "Syncer Thread" does not respond to watchdog thread
Thread "Recurrent scheduler" does not respond to watchdog thread
mean that something is not good with the server process (netxmsd).
Quote from: Filipp Sudanov on November 19, 2025, 06:58:24 PMFirst thing to check memory consumption by netxmsd, may be it goes up and system starts swapping.Supermicro X10DRi-T, 64 Gb RAM, 2x Xeon E5-2683 v3, 1 Tb NVMe SSD with paging file.
What are the specs of the machine? What DB do you use?
Quote from: Filipp Sudanov on November 19, 2025, 06:58:24 PMIs the DB on the same machine?Yes
Quote from: Filipp Sudanov on November 19, 2025, 07:03:12 PMFrom another thread is seems that you've installed with SQLite. This could be the reason for server locking.I'm aware of the fact that SQLite is not made for heavy loads and I'm going to monitor less than ten devices (home server, dad's pc, my desktop, few routers - mostly not to worry about HDDs in RAID and to be sure WireGuard is ok). But that hanging up has happened when NetXMS was freshly installed and was monitoring only itself, then I've added one MikroTik router monitored via SNMP with default settings, - which is hardly any bit of load.
Quote from: Filipp Sudanov on November 19, 2025, 07:03:12 PMI'd recommend to migrate to MySQL, MSSQL or Postgres (I personally prefer the last option, but it's just whatever you are comfortable with).I'll keep that in mind, thank you - I really appreciate your help
One you've configured parameters for the new DB in netxmsd.conf, and ran "nxdbmgr init" to initialize new databases's tables, you can use
nxdbmgr import <path-to-your-sqlite-db>
to migrate your exising sqlite database into the new one.

use Package_filter;Сам скрипт выглядит такsub main() {
packageName = tolower($alarm->key);
if(contains(packagename, "7-zip") ||
contains(packagename, "adobe reader")) {
nxlog(4, "FILTER: Blocked package - " . $alarm->key);
return false;
}
return true;

But is should be fine for a few tenths of nodes.

Quote from: Filipp Sudanov on November 14, 2025, 12:06:10 PMIn case of SQLite database login and password is not used. There is no need to check "Create database and database user before initialization". Just fill in "Path to database file", folders in that path should exist after installer finishes extracting files, so C:\NetXMS\server.db should be fine. NetXMS will create the database automatically.
