I've seen this once in a moderately loaded, network i/o bound proxy-like application. The app was running on an epoll patched R10 release (I don't recall the exact version.) I quickly looked through the sources and eventually suspected the epoll patch as culprit. Since I never saw this before on an unpatched erlang system, I stopped using the epoll patch, and after some time, eventually migrated to R11. It never happened again.
<br><br>BTW, there was little or no disk activity on this erlang node, and mnesia was not running on this machine.<br><br>Rich<br><br><br><div><span class="gmail_quote">On 10/23/06, <b class="gmail_sendername">Rudolph van Graan
