I have chat engine which is based on the Memcached variables, putting them into arrays and reading them in other end via jquery,
which works fine 95% of the times, however when the server load is high memcached (presume its the memcached) the crash and browser gets stucks up.
I dont think its jquery issue since this only happens when the server load is very high.
I need a way to monitor the memcached servers or somehow write a log file into where the fails/errors comes in...
Any idea on how i can do this ? or any idea why memcached servers fails ? I run the memcached as follows
$GLOBALS['MemCached'] = FALSE;
$GLOBALS['MemCached'] = new Memcache;
$GLOBALS['MemCached']->pconnect('localhost', 11211);
My memcached config is as follows
#! /bin/sh
#
# chkconfig: - 55 45
# description: The memcached daemon is a network memory cache service.
# processname: memcached
