appreciate it. Not sure how much memory is being used. According to our system
admin (cc'd), the total memory usage of the machine has not close to being
maxed. <o:p></o:p></span></p>

<p class=MsoNormal>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>I have posted a couple of related topics, but have not
received many responses. So, I thought I'd try again with a more general
cry for help.<o:p></o:p></p>
<p class=MsoNormal> <o:p></o:p></p>
<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>
