Marek, Thanks for all your help so far. I've applied the patch (0eff07d0fc4ef1ef3c584e71a8dd54ab708543e8) both on my development machine (to run further mprof tests) and on our test server. The local tests still show many thousands of cache items being generated, although I believe at a slightly

This appears to have fixed the problem but may have uncovered a more sinister bug. With the patch applied it seems our application now runs out of memory (so the previously seen exception was actually being triggered by a memory leak). Just to give a bit of background, the system we are

Still seeing the problem, enabled debugging on our test server and so here's the stacktrace with line numbers: System.IndexOutOfRangeException: Array index is out of range. at (wrapper stelemref) object:virt_stelemref_class (intptr,object) at System.Web.Caching.CacheItemPriorityQueue.Enqueue

@Sergey In trying to work out what may be triggering the issue, it would be helpful to know what technologies you used within your web application to see if there is any correlation with ours. We are using: Fluent nHibernate (Fluent 1.1 with nHibernate 3.0) along with the MySql.Data provider

We are in the process of trying to build a test case that will reliably trigger the bug! But considering that the system we're developing can sometimes run continuously for days without this issue occurring, finding the exact cause is likely to be very difficult. Marek Habersack wrote: The

We're seeing this too, very intermittent and with no obvious source of the problem but with the exact same stack trace reported here. This is a major issue because we can't push our new system into production with this occurring. It has occurred with both mono/mod_mono 2.8.1 and 2.10.1 running

Hello Sumit, Unfortunately no. Since it is not easy to isolate the problem in a test case (it is intermittent), I can't file a meaningful bug report. My guess is that this is some kind of a threading issue. Perhaps original developers can analyze the code and see where the potential discrepancy
