Forced "buy-in" defintion pasted 17-Feb-10 10:01 pm A short squeeze can be deliberately induced. This can happen when large investors (such as companies or wealthy individuals) notice significant short positions, and buy many shares, with the intent of selling the position at a profit to the short sellers who will be panicked by the initial uptick or who are forced to cover their short positions in order to avoid margin calls.

Another disadvantage, is that if a stock becomes "hard to borrow", which is defined by the SEC and based on lack of availibility, a broker will charge a hard to borrow fee daily, for any day the SEC declares a share is hard to borrow. This occurs without any notification to short sellers. Additionally, a broker may be required to cover a short seller's position at any time ("buy in"). The short seller receives a warning from the broker that they are "failing to deliver" stock, which will then lead to the buy-in. source: http://www.thestreet.com/story/862233/1/knowing-the-rules-of-the-shorting-game.html

Short sellers have to deliver the securities to their broker eventually. At that point, they will need money to buy them, so there is a credit risk for the broker. To reduce this, the short seller has to keep a margin with the broker.
