Do you have reproduction instructions for these crashes?
If not, are you able to reproduce the crashes with a recent version?
8.0 is three years old. We're releasing openssh-9.0 later today.

We're releasing openssh-9.0 later today.Hello, this issue was reproduced when keeping the system/OS alive ~3 minutes from start-Up. The test would be: 1-> start the system/OS (all services up & running) 2-> after 3 minutes check for crashes 3-> crash found 4 times in 460 runs 4-> reboot the system -> back to 1 again Actually, I didn't tried the latest versions due to the project restrictions, but I would like to understand what is happening -- You are receiving this mail because: You are watching someone on the CC list of the bug.

[...]> 1-> start the system/OS (all services up & running)
Which particular system/OS? All you've given us is "Linux" on
"Other"
hardware. Which distro and version? What exactly is the "other"
hardware? Has the OpenSSH been modified by the vendor?

What about the rest of it? is there a distro or is this hand built? What libc does it use? Which compiler?

We have a 32bit ARM device in our test farm so it's unlikely to be a problem specific to ARM. -- You are receiving this mail because: You are watching someone on the CC list of the bug.
