Common panic and Common Errors on Symbian mobile phones

1. Kern-exec 0 this error usually occurs when a process or thread uses a destroyed service object handle. For example, the close () method of an object is called to continue using the object handle.
2. kern-exec 3 this error is generated in many cases. The most common case is that you use a null pointer. For example, if an object is not created, use its member variables or methods.
3. User 11 memory out of bounds is usually caused by your failure to allocate enough buffer for your data. The value of a string exceeds the value of imaxlength.
4. If the rarray or rpointerarray subscript you access exceeds the array length, this error occurs.
5. User 29 most of the errors are caused by an out-of-bounds operation on the index of the sub-string of the descriptor.
6. User 42 this error is usually caused by illegal memory access. For example, the access point is a pointer to invalid memory.
