I'm not sure if this is actually blocking page views because I can't reproduce it myself. I noticed this in the error log today:

....

There were scores of these today in both session.inc and cache.inc.

I'm running PHP 5.2 on a FreeBSD 6.2 box w/MySQL 5.0.33 and very few third-party modules.

Could this be related to PHP 5.2's new object memory management which was causing problems with the $user object disappearing in session.inc v4.6?

Actually, I just reproduced it. I turned off caching this evening, turned it back on and hit the home page as an anonymous user. The first page hit didn't dump an error to the log (possibly because it hadn't been re-cached) but subsequent hits spit that session.inc and cache.inc error into the error log.

The page displays fine but I suspect it may not be hitting cache because of this error.

I'm running with a 5 minute expiry on the cache, if this matters. No CSS aggregation. And APC.

Also, Caching mode = Normal.

I plugged some debugging code into cache.inc and hit the (cached) home page as an anonymous user:

------------------
function cache_get($key, $table = 'cache') {
global $user;

print "

"; print_r($user); print "

"; exit; // <<
...
-----------------

This the $user object that the function is seeing with cache enabled for anonymous users:

stdClass Object
(
[uid] => 0
[hostname] => 192.168.1.2
[roles] => Array
(
[1] => anonymous user
)

[session] =>
)

$user->cache doesn't exist in the object.

Same here. I'm also having issues with changing Site Name and defaulting a new theme. Think it's related?
