Updates:
I'm pretty sure I am dealing with a WP issue, unrelated to Cherokee. But
since I started this thread, I figure I should finish it. In case anyone
finds this thread with google, I should set the record straight.
1. I made sure the Cherokee IO Cache is enabled.
2. I installed the Wordpress SuperCache plugin. It appears it is really
built for apache and only "half supports" other servers.
3. I reduced my php memory_limit to 64MB, in case grabbing for more memory
was causing thrashing. No effect.
I am getting *lots* of 500 errors, lots of partial pages and occasional
"could not connect" errors, all of which are corrected by a page reload.
I am seeing all of this with both Firefox 3.6 and IE8.
What I'm seeing in my logs is this:
{'type': "error", 'time': "24/07/2010 20:10:39.594", 'title': "ALERT -
script tried to increase memory_limit to 268435456 bytes which is above the
allowed value (attacker '<ip-address>', file

", 'code': "handler_fcgi.c:118", 'error': "42", 'version': "1.0.5",
'compilation_date': "Jul 7 2010 01:32:03", 'configure_args': "

where I have used <expressions> in angle backets to conceal my site. Note
the very large amount of memory which the fcgi is requesting! It is
interesting to note that 268435456 = 0x1000 0000 = 256 MB which seems a
little suspicious to me since phpinfo() is correctly reporting that it is
reading memory_limit=64M from the /etc/php5/cgi/php.ini file.
If I dig into the stock wp-admin.php, I find this at lines 95-96:
if ( current_user_can( 'manage_options' ) )
@ini_set( 'memory_limit', apply_filters( 'admin_memory_limit',
'256M' ) );
It looks like wordpress is asking for an awful lot of memory.
So I still don;t have a solution to my problem, but I think I have an idea
of what the problem is, and I'm pretty sure it has nothing to do with
Cherokee.
