Hello!<br>
<br>
Do you have any log? Are you able to replicate such a behavior
consistently? If so, could you please share an exact configuration
with us to put it into our testbed?<br>
<br>
You can also enable "debug protocols all;" in your conf file. This
produces a s***load of logs, yet it should yield enough clues to
isolate the problem and find a suitable solution.<br>
<br>
Thank you for your report! <br>
<br>
Maria <br>

<pre dir="auto" class="k9mail">Hi all.
I have Bird 2.0.8 on one of border routers, it runs with kernel 5.10.26
and uClibc-ng 1.0.38. It acts as RR and receives FV from uplink + FV
from second border (also RR), and it has 2 routing tables (one which
receives BGP routes, then routes sinks to main table.
When second border's BGP link fails, Bird starts to rebuild routing
table, and acts quite strange (too slow birdc response, etc) and after
~5 minutes OSPF looses neighbors and falls to state 'Alone'. It can be
in that state for hours, and initiated only after bird restart (I didn't
tried protocol restart - usually I don't wait for end of route table
recalculation).
When table recalculation is in progress, perf top shows that 40+% CPU
time is used by malloc routine.
Are there fixes in trunk for such behavior? If no - what extra info is
needed for debugging?
