Error in Coldbox.system.cache.policies.LRU

Communities ColdBox HMVC
1

I get this error randomly on my main site. It happens on multiple servers at random times. Does anyone have any idea why this might happen?

I’m not 100% sure but I believe this is caused by an Async Thread during the cacheBox clean-up period.

Open to ideas or suggestions…

WOW, that basically says the pool is null. Weird. Only way I can see this happen is on restarts or rein its

and the strange thing is that I haven’t restarted these servers for days if not weeks - and this happens several times a day?

could this be a railo bug?

I have a similar error that happens intermittently, usually on a bot crawl with a high number of concurrent requests. It is on a CF10 machine so the error message is a bit different. I believe it is caused by the cache expiration occurring during the processing of the request. I’m unable to duplicate the error in development. I’ve chosen to ignore the issue up to now and keep an eye on it for the time being. That said, I should probably implement a cache decorator with named locks, per the docs: http://wiki.coldbox.org/wiki/CacheBox.cfm#Caching_Considerations .

Hi Jeremy,

I am getting a similar error on a SUN OS server.

Error creating eviction policy: LRU
Could not find the ColdFusion component or interface LRU. Ensure that the name is correct and that the component or interface exists.

Glad I’m not the only one :slight_smile:

I agree – Jon! It happens MOST often when Bing or the chinabots scrape my servers rapidly. I will usually see 50-200 errors on Thursday & Saturday nights late. The rest of the week it rarely happens.

On occasion I will see it happen with I have large spikes of traffic however nearly ever time my site spikes above 200rps - its all to just a handful of pages. Whereas the bots scan hundreds of pages over a minute or two.

I know none-of-that helps but just trying to someone else spark an idea of what might be causing it.
