These panic numbers represent errors which cause the Kernel itself to terminate. +When the kernel terminates for the reasons listed here, it is said to fault +rather than panic.

The faults themselves are raised by kernel side code.

Note: many of the faults listed here are raised in debug builds +only.

+ + + + +

Fault number

Reason

+ + +

0-3

Not used.

+ + +

This fault is raised when a system thread has panicked or terminated +causing the entire system to re-boot.

+ + +

Not used.

+ + +

This fault is raised when adding a code segment, a DCodeSeg object, +to the dependency table of another code segment.

The fault occurs +when the number of dependent code segments added exceeds the maximum expected, +suggesting some inconsistency.

Note: DCodeSeg is +internal to the Symbian platform.

+ + +

Not used.

+ + +

This fault is raised when the thread that deals with raw hardware +events, as generated by the hardware drivers of a pointer device, a keyboard +etc., has terminated. The thread is referred to as the thread event hook.

Note:

The most common cause +is the death of the window server "wserv".
Raw hardware events +are represented by TRawEvent objects.

+ + +

This fault is raised when an attempt to allocate the buffer that +is to contain raw hardware events (as represented by a set of TRawEvent objects), +cannot be allocated.

+ + +

10-14

Not used.

+ + +

This fault is raised when a thread or process is panicked or terminated +when one of the following is true:

the kernel is locked.
the current thread holds +a fast mutex.

+ + +

Not used.

+ + +

Not used.

+ + +

This fault is raised by internal functions, which as part of their +implementation, fetch a DObject based on the object type, +a TObjectType type.

The fault occurs when the value +representing the object type lies outside the permitted values.

The +fault can also be raised by Kern::ObjectFromHandle().

Note: TObjectType is +internal to the Symbian platform.

+ + +

Note: DSession is +internal to the Symbian platform.

+ + +

Not used.

+ + +

This fault is raised by a kernel side session (DSession) +object's destructor if there are still messages outstanding on that session +by the time the destructor is called.

Note: DSession is +internal to the Symbian platform.

+ + +

Not used.

+ + +

This fault is raised by a kernel side server (DServer) +object's destructor if there are sessions still attached to that server by +the time the destructor is called.

Note: DServer is +internal to the Symbian platform.

+ + +

This fault is raised by a kernel side server (DServer) +object's destructor if that server still has messages that have been delivered +but not yet accepted by the time the destructor is called.

+ + +

This fault is raised by a kernel side server (DServer) +object's Close() function if that server still has messages +that have been delivered but not yet accepted.

+ + +

Note: DSession is internal +to the Symbian platform.

+ + +

This fault is raised in debug builds only.

This +fault is raised when a message is being freed and the message appears to belong +to an unknown message pool.

+ + +

Note: DSession is +internal to the Symbian platform.

+ + +

30-40

Not used.

+ + +

This fault is raised when the DFC that is used to restart the second +absolute timer queue (TSecondQ) finds that the queue is not +locked.

+ + +

This fault is raised by the DLogicalChannel destructor +if there are outstanding messages by the time the destructor is called.

+ + +

+ + +

58-62

Not used.

+ + +

This fault acts as a trap if a thread calls NKern::ThreadKill() to +terminate itself, and the call to that NKern::ThreadKill() function +returns. When a thread calls on itself, the call should not return.
