I have not been able to figure this out. Killing and restarting it is not an option as I have limited abilities on the server. Is there any way to clear memcached?

After clearing my filesystem cache and rerunning the app, I never got any more files written in, but the site felt faster. ThankS! This worked perfectly, thanks for the how to.

Me thinks that error is a red herring. More digging (!) is needed on this one. A little update, I got the same error:

Using memcached for Ruby on Rails session storage
Posted by Stefan Kaes on Tuesday, January 24, 2006

A few days ago Eric Hodel announced the availability of a new pure Ruby memcached client implementation (memcache-client-1.0.3) with performance improvements over the older Ruby-Memcache-0.4Roll your own SQL session store). implementation. I had measured the old version previously, for use as a Ruby on Rails fragment cache storage container, but found its performance to be abysmal and completely unusable for my purposes. memcache-client-1.0.3 provides much better performance: much faster than either the old implementation, pstore or ActiveRecordStore, but also faster than my optimized SQLSessionStore using MysqlSession

So I uninstalled memcache-client (it was version 1.0.3) then installed the newer client, Ruby-Memcache (it was version 0.4 - but it is found under databases/rubygem-memcache-client in the FreeBSD ports) and all seemed to be fine, if it’s faster or not I can’t tell just by myself, but if you want to ‘edit’ a post -or- submit a comment to a post it throws the following error:

Application error (Apache)
Change this error message for exceptions thrown outside of an action (like in Dispatcher setups or broken Ruby code) in public/500.html

I had to uninstall the newer memcache client and go back to the older client just to post this! I’m going to post this on the Typo list to see if it’s Typo, or Rails related. Where is Apache getting thrown into the mix? I use it to do the mod_proxy to ip:3000 so it hits Typo, but I’ve never gotten an error in Typo that is Apache based (afaik).
