<br>
</span>Hi<br>
<br>
I would like to confirm, it is BIRD that was killed by out of memory<br>
killer and could be just restarted? Or Linux kernel crashed? (You wrote<br>
'the kernel crashed with out of memory issue' in one prior mail.)<br>
<br>
In the first case, how much memory BIRD takes after start and before it crashes?<br>
How long it takes to crash to crash due to OOM?<br>
