Okay !! I just made all my filesystem except root ext2. (I couldn't boot when I configed out ext3 - mounting root failed).
Anyway, problem seem to have gone away.. Machine is really slow while trying to do IO on all 4000 filesystems. It is slowly creating processes. System is 100% busy. (so far, it created 461 processes out of 4000). But we are not running out of lowmem and inode caches seems to be reasonable..
So, it must be some leak in ext3..
