HORUS crashes

[Anpu]

Hi all,
I m experiencing tons of crashes on Horus in very small time (about 4 crashes in 2 mins).
While on Ra I rarely crash, on Horus I crash a lot.
I checked my settings for Horus and they are same as for Ra.
Here are 4 crashes today that happened in couple of miutes (first one happened when I first entered in world):
