I've noticed in 2.5.3 that I've started getting a lot of these
"An exception has occurred during action 'FindUsages' update ---> System.Exception: Error generating from file: ...\CoreProductControl.ascx ---> System.OutOfMemoryException: Exception of type 'System.OutOfMemoryException' was thrown.
at System.Collections.ArrayList.set_Capacity(Int32 value)
at System.Collections.ArrayList.EnsureCapacity(Int32 min)
at System.Collections.ArrayList.Add(Object value)
at JetBrains.ReSharper.Util.OneToManyMap.AddValue(Object key, Object value) in c:\Agent\work\Server\ReSharper2.5\src\Util\src\dataStructures\OneToManyMap.cs:line 65"
Once it starts happening I have to restart visual studio. It seems to affect aspx/ascx files mostly. It seems worse with the latest version
