Types of System Crashes
Address Error
Address errors happen when the software tries to get to information on inaccurately adjusted limits; two-byte and four-byte accesses are permitted just on even addresses. An address error for the most part shows a software bug, yet flawed hardware can likewise be a cause.
Arithmetic Exception
A software issue for the most part causes this kind of error.
Cache Error Exception
This kind of crash occurs because router finds bad parity. For information on the most proficient method to investigate this issue, refer to Processor Memory Parity Errors.
Error Interrupt
An error interrupts with a crash that is other than the processor identified a fatal error. You require more data to decide the underlying driver issue cause. A crashinfo record or show technical support charge yield is required to investigate. After you have gathered this data, contact your Cisco specialized bolster agent.
Format Error
Unless the circumstances unmistakably indicate a hardware issue, contact your Cisco specialized spport agent about this error.
Illegal Instruction
This error is frequently software related. However, broken equipment can likewise precipitate this issue. This issue can likewise happen because of a corrupt Cisco IOS Software picture.
Illegal Opcode Exception
An equipment failure causes this error (for instance, the failure of the CPU board). At times, a software issue can bring about this error.
Jump to Zero Error
This sort of mistake regularly happens when the Cisco IOS Software tries to execute information rather than code. More often than not, a software bug causes this issue, yet in the event that the side effects, plainly indicate a hardware failure, think about how possible it is of a faulty CPU.
Line Emulator Trap
A line 1010/1111 Emulator Error happens when the processor tries to execute an invalid guideline. The code 1010/1111 is not by any stretch of the imagination significant (the code relies on upon the invalid direction you attempted to execute).
The main reasons for line emulator trap errors are:
  • Faulty Flash memory or DRAM
  • Software issue
  • Power-On
Reserved Exception
For this kind of crash, a reload happens keeping in mind the end goal to guarantee that the router does not transmit degenerate information. The cause can be either equipment related or software related.
Restarted By Error
Unless the error clearly indicates an equipment issue, contact your Cisco technical support agent.
Sigtrap (Signal Trap) Exception
This is normally a software issue, and is another approach to report a Software-constrained Crash.
Undefined Trap
Unless circumstances plainly show a hardware issue, contact your Cisco technical support agent.
Unexpected Hardware Interrupt
An equipment issue regularly causes this sort of crash.
Unknown Failure
Unless circumstances obviously demonstrate an equipment or hardware issue, so you need to contact your Cisco tech support agent.
Unknown Reload Cause


Here, the defect that created the crash does not permit the router to record the reload reason. This issue can be identified by the software. Unless circumstances unmistakably show an equipment issue,so you need to contact your Cisco tech support specialist agent.
