We've run into the "LACP restarts during a write mem" bug too, and it prevented us from upgrading beyond FTOS 7.7.1.1 for a long time. <br><br>I can report that this particular bug has been fixed in the latest versions, and we are now running on 8.3.1.x, with no real problems after several weeks. <br>
<br>Sameer, I'd suggest upgrading to the latest code, and see if the problem still exists. <br><br>Adam Waite<br>Network Engineer<br>Tuenti Technologies<br><br><br><div class="gmail_quote">On Fri, Jul 9, 2010 at 11:09 PM, Matt Hite <span dir="ltr"><<a href="mailto:lists@beatmixed.com">lists@beatmixed.com</a>></span> wrote:<br>

and port channels go bye-bye during a write mem. It's not always<br>
reproducible but it is definitely an issue.<br>
<br>
There's a PR #79439 which is fixed in 8.3.1.3 (S series).<br>
<br>
It's a guess, but you may try to get 8.3.1.3 installed and see if it helps.<br>
