We have a site running corectly with 4.5.1 that includes the DNN forum module.

In upgrade to 4.5.2 we can no longer access the Forum home page or the forumm module. The system times out with the error below. To be sure, we rolled back - ckecked it all and things were fine. Then updated again with the same problem.

Na, the problem is not that.

Server is a spanking new Multi processor jobbie with ECC and 8 GB ram.  That's not the issue. Worker process set on a seperate instance for that site. hardly anything else going on on that server. Seperate SQL server. WP set to unlimited ram.

There is something wrong!

What is happening is that a language resource file is being read in to memory.  When XML methods are used it reads in the whole file to memory.

There might be something wrong with one of resource files, so I would compare them before and after.

Unrelated, but my advice on the caching is to never set it to "no caching".
