Hi,<br>
<br>
These machines are running 32-bit OS (but the chip itself is a 64-bit
xeon). Memcached 1.2.2 with libevent 1.3b. I would expect it to be able
to use up to 4gb of space but any more than 2 it seems to get unstable
and crash. <br>
<br>
I've tested this on a 64-bit machine and it seems to eat as much memory
as we throw at it. <br>
<br>
Is the moral of the story "use 64-bit"?<br>

<pre wrap="">Which memcached version? Which system architecture (AMD64, etc.)? Which
libevent version? If you were running it on a 64-bit architecture, was it
compiled as a 32-bit app or a 64-bit one?
Our memcached instances are all 13GB and they all run until we have to take
the machine down or install a new version. We compile in 64-bit mode and
memcached happily chews up all the memory we throw its way.

<pre wrap="">Hi,
We've seen corruption too on some older linux kernels (2.6.11) with
memcache instances larger than 2gb (no idea why) this would cause weird
issues and if we kept using it would eventually crash by themselves
after a few days. we saw this on 4 different machines. When kept under
2gb they seemed stable. Perhaps this is your issue?

Is this common practice? Does anyone have experience running
memcached for months on end with no data corruption?
Thanks.

That is 65 days. And we took it down then to physically move the
server. We don't even think about it. It just runs. No issue with
"data corruption", whatever that means.
