The cause is that your code is not closing files and the system is running out of file handles. You should always use files using a coding pattern that ensures that all streams are closed when no longer needed. Here's a typical pattern:

InputStream is = null;
try {
    is = new FileInputStream(myFile);
    // read stuff from is
} finally {
    if (is != null) {
        try {
            is.close();
        } catch (IOException e) {
            Log.w(LOG_TAG, "Exception raised when closing file", e);
        }
    }
}

The outer try could also have a catch clause. The reason for the try/catch in the finally clause is to prevent an exception in closing the file from suppressing any exception raised in the outer try block.

Writing to files tends to be less of a problem because programmers usually take care to close the file to ensure that the data reaches the file. However, a similar pattern should be followed there: never let an exception prevent the closing of a file.
