I'm posting this here, in the hope someone may have seen this issue before.  One of my clients sites has a problem where an error seems to get into an infite loop and fills the event log and makes the site crash.

This has happened 3 times now over a 6 month period, it seems impossible to create at will. 

I suspect the error may be due to an error in the langauge resource files, but this is just a guess as I can;t recreate the issue on demand.

The fix is simple, I just restart the website and clear down the event log.  But obviously this is not a suitable solution for the furture.

here is the error...

-----------------------------------------------------------------------------------------

System.IndexOutOfRangeException: Index was outside the bounds of the array.     at System.Collections.Generic.Dictionary`2.Insert(TKey key, TValue value, Boolean add)     at System.Collections.Generic.Dictionary`2.set_Item(TKey key, TValue value)     at DotNetNuke.Services.Localization.Localization.GetResourceFileCallBack(CacheItemArgs cacheItemArgs)     at DotNetNuke.Common.Utilities.DataCache.GetCachedDataFromDictionary(CacheItemArgs cacheItemArgs, CacheItemExpiredCallback cacheItemExpired)

Any ideas or suggestions are welcome.

Thanks.

Hi Sebastian,

It's running on v5.6.1, which was ungraded from v4.5. I'm relunctant to do any upgrade from v5 to v6, at the moment I'm only trusting fresh installations of DNN6 to go live.

It running just the fr-FR langauge, en-US having been disabled.

I've read a few posts relating to errors which are similar, but nothing that hits the nail on the head!

Of course my last resort is to rebuild as a fresh installation, but as you can image, with all the data that needs moving, this could prove very difficult.

Dave.

Upgrade site to DNN6 and new server 3 weeks ago and so far no more problems.

I think this could be down to a combination of an underpowered server and the DNN5 bug.
