Now it has 48 GB allocated, on the older version it ran without problems on 32 GB.

I don't remember exactly what version it was. The problem appears from versions from about October/November. We update about once a month.

From stack trace it looks like netxmsd run out of memory. Can you please show chart of memory consumption by netxmsd?

Best regards,
