Performance problem on build

Hi All.

For the some latest build we have serious performance problem when pressing the build button.
After the message Checking Dependencies appeared in status bar, IntelliJ is stack for long.
We took snapshot of it and inspected it with YourKit, we can see that most of the time is spent on method:
com.intellij.compiler.make.DependencyCache.hasOverrideAnnotatedMethods(int, Project)


I also want to mention that there are sometimes the compilation is ended without this delay - even if not all files are up to date.

I tried to upload the snapshot file to ftp://ftp.intellij.net/.uploads/ , but always get the same error:
550 Security server forbids that action on this file

Please your advice.
