What ends up triggering it is some file-system change (for example: anti-virus, a machine.config file reset, disk cleanup, etc) that causes a timing error that exposes a race condition with the compilation system. The QFE should fix it - although we have seen a few cases where people have reported that it hasn't (what often happens is that it stops recurring once we try and look at it). We haven't completely figured out why it still fails when the QFE is applied - but if you have such a case please let us know and we'd like to debug. As a workaround if you can't install the QFE, you can set <compilation batch="false"> in your web.config file. This should also avoid the error. Hope this helps, Scott http://ayende.com/2274/asp-net-wtf-sorry-blog-was-down#comment3http://ayende.com/2274/asp-net-wtf-sorry-blog-was-down#comment3Mon, 02 Apr 2007 04:03:25 GMTsee http://web-designing.inusinternational.com/Asp.net.asp http://ayende.com/2274/asp-net-wtf-sorry-blog-was-down#comment2http://ayende.com/2274/asp-net-wtf-sorry-blog-was-down#comment2Sat, 31 Mar 2007 21:19:32 GMTAyende, Please post more about this if you discover anything interesting. I have seen this before, but it seemed to occur without any rhyme or reason. http://ayende.com/2274/asp-net-wtf-sorry-blog-was-down#comment1http://ayende.com/2274/asp-net-wtf-sorry-blog-was-down#comment1Sat, 31 Mar 2007 20:04:39 GMT
