When the machine slows down, how much free physical memory does the
machine have? Is the entire memcached process memory-resident, or has
the OS started to swap it out? The instant memcached starts having to
swap, its performance plummets. The behavior you describe is consistent
with a memcached instance growing larger than the available physical
memory over time. When you restart it, it would start small again and
not need to swap.<br>

<p class="MsoNormal">We have a FreeBSD server running a variety of
php (web
based) scripts that access/use memcached (latest version). We have
found that the machine, after a period of time begins to slow down.
And,
when we restart memcached it picks back up. Any ideas you have as to
why
this might be happening would be greatly appreciated. I will gladly
provide more information if needed. I am not sure what to provide
though. In genaral, I am would just like to know what might be causing
thing or what might be happening.<o:p></o:p></p>
