Description

Reviewing status outputs for 24.03. I began to notice frequent pftop core dumps (signal 10 and 11). These are displayed in the message buffer and system.log.

pid 57704 (pftop), jid 0, uid 0: exited on signal 11 (core dumped)

Subsequently I discoverd a pftop.core file in `/root` of my own system (attached).

# file pftop.core

Seeing this on my 24.03 VM too. In my case it seems to always happen very shortly after logging in to the GUI. It doesn't seem to affect anything however. Diagnostics > pfTop and States still work fine.

I wasn't able to trigger this by logging in. One thing I did notice is I've only seen this on amd64, nothing from my 2100 (arm64).

Updated by Kristof Provost about 2 months ago

I've pushed a fix for pftop crashes (specifically seen with `pftop -f icmp`) to the 25.03 and plus-devel-main branches. This may or may not be a root cause fix for this issue as well.

On 24.11 I couldn't get pftop to crash consistently. Until I initiated some pings, so there was some ICMP states.
At that point pftop would crash every time I ran `pftop -f icmp`

I upgraded to 25.03-RC and the problem is resolved. Thanks!
