strange 503 service unavailable

[justjay202]

I can see my main Magento site, can access a wordpress site within the folders of Magento, but can't access the xcache-admin site.

Can anyone shed any light?

I see this error in the server logs:

when access beta.jgoodin.com/xcache-admin now,

"XCache is not loaded
Please check /usr/local/lsws/lsphp5/lib/php.ini"

I disabled xCache as it was causing this 503 mess. I don't know what it was.

I found this in the stderror.log file..

Don't know if that points to anything?

what's the settings of xcache ?
find it in php.ini or phpinfo()

[justjay202]

; zend_extension=/usr/local/lsws/lsphp5/lib/php/extensions/no-debug-non-zts-20060613/xcache.so
; xcache.cacher = On
; xcache.test=Off
; xcache.size = 256M
; xcache.count = 4
; xcache.var_size = 32M
; xcache.var_count = 1
; xcache.var_slots = 8000

; xcache.mmap_path = "/tmp/xcache"
; xcache.readonly_protection = Off
; xcache.optimizer = On
; xcache.coredump_directory = "/tmp/"
; xcache.coveragedump_directory = "/tmp/pcov/"
; xcache.coverager = Off

[below that my user settings]

the cache's size(256M + 32M) may be too big. it may exceed php process memory limit so those errors in stderr.log
