Hi Victor,

i downloaded and installed NetXMS V4.5.1 a few minutes ago (all ok, NetXMS is running so far). Now i see, that the V4.5.1 version was withdrawn from the website...

Are there serious problems with V4.5.1?

Greetings
Marco 

No, it's just a website issue -- it was rolled back to previous build by accident. It will be updated shortly.

UPDATE: it's back

Since the update we are experiencing the following segfaults.

Is there anything we can try to prevent this?

We use Ubuntu Server 22.04 with all updates, PostgreSQL 15.5 and TimescaleDB 2.13.1 extension.

Update, output from debug run:
Thread 196 "$POLLERS/WRK" received signal SIGSEGV, Segmentation fault.

Confirmed, no longer crashing when this option is enabled.
Also, the option itself works
