[Ocfs2-users] Did anything substantial change between 1.2.4 and 1.3.9?

You're right, it -is- possible, but if you look at it (and I can log
it for hours) it only seems to do that right before I get a timeout
message from the proxy. The two appear to be related.
I will continue to monitor this and make sure that my hypothesis is
correct. Something is flaking out every so often.
I get this on my nginx proxy server:
2008/04/21 17:37:01 [error] 1256#0: *7406286 upstream timed out (110:
Connection timed out) while reading response header from upstream,
client: 1.2.3.4, server: lvs01.domain.com, request: "GET /someURL.php
HTTP/1.1", upstream: "http://10.13.5.12:80/someURL.php", host:
"somedomain.com", referrer: "http://somedomain.com/someURL.php"
That only happens after it's sitting for 3 real-time seconds waiting
for a reply from the server. Note: this happens no matter what proxy
and webserver I use. It does not seem to be anything related to that.
