For an operating system to function efficiently, it should be synchronized with the various units in the system. There are chances of experiencing a system crash, eventually with a data loss when any of the units fail to connect. “Kernel Panic” is one such system crash.
On the off chance, if an operating system encountered a fatal error internally and unable to recover from it, then the operating system implements a safety measure known as “kernel panic” to stop the system from running and eliminating huge data loss. Majority of the users have come across this situation when a normal working system restarts all of a sudden and the work done since you last saved will be lost.
Causes For Kernel Panic
Kernel Panic can be caused by a number of reasons. Few suspected reasons have been mentioned below
- An inappropriate attempt by OS to read or write memory
- Improper installation of RAM chips
- Defective microprocessor chip
- Malware or software bugs
- Data corruption
- Hard-disk damage
How To Detect If It’s A Kernel Panic?
The term “Kernel Panic” is primarily applied to MAC OS X and UNIX based systems. In Windows, it is known as “general protection fault’, “blue screen of death” etc. Let’s explore how to detect a Kernel Panic in each of the operating systems.
On OS X 10.7 version and it’s earlier versions, the screen produces an alarm and fades to black containing a message to restart. In OS X 10.8 version and it’s later versions, the system simply restarts without any warning, followed by a message explaining the issue briefly.
On Linux systems, the operating system can deal with the serious error and continues to run known as Kernel Oops. Eventually, instability occurs and lead to Kernel panic displaying a black screen full of code.
On Windows you will find the whole screen turned blue, displaying a message to restart the computer.
Kernel Panic Troubleshooting
A log will be created containing the information of what occurred at each occurrence of a kernel panic. Even though the information is incomprehensive to the normal users, the technicians can effectively diagnose and resolve the issues considering then the information in the log.
Let’s explore how to troubleshoot a few common causes
In order to diagnose the software issues, you need to boot into Safe mode to load the core elements of an operating system. Linux doesn’t have a safe mode but a recovery partition. In Windows, you could boot into safe mode by holding F8 when restarting, whereas, in Mac, you need to hold the shift key after the occurrence of a startup chime.
Let’s have a look on how to troubleshoot the software issues
Keep Your System and Software Updated
Always keep an eye on the updates announced frequently. Make sure that your operating system including the drivers has updated to the latest version and also the software. Check for the programs that are launching on boot and disable the ones which you have installed shortly before the occurrence of kernel panic and then re-enable.
Make Use Of System Restore
The unsaved changes made to the system will be lost on the occurrence of Kernel panic. Hence it is vital to use Time Machine or System Restore to roll back to the state before Kernel panic occurred.
A key to effectively identify the exact cause of kernel panic is to identify the recent changes to your system, undoing the changes and then try re-enabling one by one.
Look For Disk Errors
To ensure disk errors are not causing a Kernel panic, you need to run the disk repair software built into your computer’s OS. As soon as your computer boots, if it crashes you have to boot into the recovery partition. To do this press Command + R on Mac and F10 on Windows. You can carry out booting from a disk or USB.
If you have upgraded the RAM on your system recently, check if is placed properly. Try removing the RAM if the problem still continues and if the issues are resolved, you should understand that the RAM is faulty and you have to contact the retailer.
Often we believe that large add-ons alone cause issues. But Kernel panic can happen even if there is a fault in your USB. You can re-connect the peripherals confirming if there is no fault.
Kernel panics are common and you will be experiencing it time to time. If you experience them on a regular basis, then it is obvious that the recent changes done to the system has caused it. However it’s not a wider problem and as long as you’re prepared to deal with it, it is easy to diagnose and resolve.
5 Amazing Ways Switching to a Dedicated Server will help your Business
Choosing a server is a vital step for any online business. Your decision will not just decide where your data gets stored, but it also becomes a major factor for your website performance. You have three major options – shared hosting, dedicated hosting or cloud hosting. But dedicated servers are special for your online business. Why?
While Cloud hosting definitely offers numerous advantages, it is not an ideal solution for small businesses since business needs being basic and the inflexible operational nature of cloud. Hence a dedicated server is the wise choice in most cases.
How will it help your business though?
1. Reliable Data Centers to secure your data
When you buy a dedicated server, it is usually set up in a large facility with a number of other servers. These facilities are known as Data Centers and have amazing internet connection speeds to ensure reliability. Not just that, they will also have high security features including physical security. There would also be engineers to tackle any emergency situations. Data Centers are built with the sole purpose of securing your dedicated servers. It keeps things simple. You don’t have to worry about your data’s security. The more secure your data is, that much better it is for your business.
With the relevant technical expertise, you can easily make use of dedicated servers’ flexibility. If you want to add some third party software for security or if you want to change the control panel, it’s all a walk in the park with the root access. You can make any specific settings or changes. If you are someone who updates your server side on a regular basis, then these customization options make it very user-friendly for you.
3. Long-term View
As a brand, you might be popular, but you are making the shift to the online world now only. In such cases, it’s natural to consider that you have huge traffic potential. If you are aware of your growth potential, isn’t it better to be prepared for the traffic surge? Even if you are not an established brand, but has huge traffic as long term goal, then it’s wise to have a dedicated server in place.
Compared to VPS or shared hosting, dedicated servers come with higher bandwidth. And being a dedicated server, there would be a processor and RAM dedicated exclusively for you. Keep in mind that with shared servers you have to share server space with hundreds or even thousands of other customers. No online business would flourish without a solid web presence. It adds to your business in numerous ways from providing good user experience to better google rankings.
5. Cost and Simplicity
While it might seem that a dedicated server is higher in cost than shared ones, dedicated servers provide better value for the money you spend. They offer better security and due to their simple infrastructure,they are very easy to maintain. Compared to cloud, dedicated servers are quite simple. Simpler is better as you won’t have much complications during emergency situations.
