The Deep Space Kraken is a bug in the game that is experienced in deep space. It is an error with the games physics engine, PhysX, which attacks spaceships as their velocity increases. The number of parts in your ship has a large effect on what speed the Kraken Manifests itself, as well as how much it affects your ship. It primarily causes your craft to go off trajectory due to forces that shouldn't be there.
The cause of this bug is extreme velocity; the bug subtly exists even in Kerbin orbit, though is mostly only noticeably experienced in Kerbol orbit due to velocity you "gain" when you transition SOI to Kerbol. A fix was implemented in 0.17, involving offloading velocity to the universe around you meaning that the focused vessel will always be at a somewhat low speed. However, the same bug under a new name, the space Cthulhu, can break apart ships when quickly warping out of high time accelerations (as of 0.17). It has been reported that Cthulhu can attack ships that are still on the launch pad when coming out of a high time warp.

Variations
General Kraken
General Kraken or The Kraken is a less serious form of Deep Space Kraken and mainly occurs during interplanetary travel. General Kraken only breaks a few parts of a spacecraft which may then collide and result in explosions. The Kraken may also force parts slowly through each other and result in catastrophic explosion. Unlike the Cthulhu, the Kraken tends to attack when exiting the Map View and IVA mode.
Gyro Kraken
Gyro Kraken is when a spacecraft will spin around vibrate so intensely that the spacecraft will be obliterated. The rate of spinning is so extreme that it is impossible to be replicated manually.
Warp Kraken
Warp Kraken is an 0.19 bug that attacks kerbals exiting spacecraft that have just come out of a high time warp. Upon contact with the surface the bug causes the kerbal to be shot out of the solar system at an insane velocity (possibly exceeding the speed of light) while destroying all spacecraft in the vicinity. This bug has so far only been encountered on the Mun and has not been confirmed to exist in 0.20.
Deep Space Cthulhu
Deep Space Cthulhu is a fan-made term for a version 0.17 bug similar to the Kraken, except it only seems to attack when exiting high time warp speeds. Instead of adding phantom forces, Deep Space Cthulhu instead tends to detach parts from one another. In milder, yet more infuriating forms, Deep Space Cthulhu will instead detach small groups of engines, making it impossible to perform orbital burns.
Cthulhu is a cosmic entity from H.P. Lovecraft's novels, and bears a slight resemblance to a Kraken.
EVA Kraken
The EVA Kraken is a 0.20 bug that spectacularly destroys a spacecraft if a kerbal on EVA approaches it at high speed. It only occurs in fairly specific circumstances. A kerbal must EVA from a ship and go far enough away that parts physics stops acting on the ship (200 metres). Then if the kerbal comes within 200 metres again at high speed there is a chance the ship will explode in spectacular manner, with the debris shooting off at high velocities (sometimes enough to escape low Kerbin orbit). Sometimes the unfortunate kerbal will be killed as well.
Causes
The reasons behind this form of kraken are not well understood. It is possibly due to the parts clipping into each other as physics starts to act, or another theory is that it is due to physics trying to start too quickly to keep up with the rapidly approaching kerbal. At the moment very little concrete data exists. What is certain is that it always starts as the kerbal passes exactly 200 metres from the craft, and that it only occurs when the kerbal is moving at relatively high speeds. The kerbal does not have to come from the ship it destroys. It is unknown what happens if physics starts to act on multiple ships at once.
Prevention
There are good reasons to take precautions against EVA kraken as it always destroys the affected ship completely. The best prevention tactics known so far is to approach ships slowly and quicksave often.
Changes
- (Bug fix) 'Off loading' velocity to the universe alleviated this problem, though it still exists in 'new' format
