Introduction
This article provides a step-by-step guide in resolving the Run-time Error (forrtl: severe (41): insufficient virtual memory) with effective solutions, as well as answers to the most frequently asked questions of the error.
What Is "forrtl: severe (41): insufficient virtual memory" Error?
The ‘forrtl: severe (41): insufficient virtual memory’ error message is a common error for Fortran programs. It indicates that the computer does not have enough virtual memory to run the program, due to either an insufficient amount of disk space or a large memory limit being set.
How to Fix the Error
The following steps outlines a method to resolve this issue and get back to normalcy:
Check Memory Available: The first step in handling the ‘forrtl: severe (41): insufficient virtual memory’ error is to check the amount of memory available on the system. This can be done with the Windows Task Manager, or in macOS by selecting the Apple menu and then selecting ‘About This Mac’.
Check the Program Use of Memory: Once the amount of memory available has been established, then it is time to check the program use of memory. This can be done by checking the size of the program in bytes. The larger the program, the more memory it will take to run it.
Check System Hard Drive Usage: Another factor that can lead to the ‘forrtl: severe (41): insufficient virtual memory’ error is the amount of hard drive space being used by the system. If the computer’s hard drive has become full, then it may not have enough resources to allow the program to run.
Reduce Memory Limit for Program: If the program is consuming too much hard drive space, then it can be reduced by changing the memory limit for the program. By reducing the memory limit, the program will use less memory and may be able to run without any further issues.
Check for Memory Leaks: Memory leaks can also be an issue, as they can cause the program to take up more memory than is necessary. One way to check for memory leaks is to look at the size of the program’s memory usage in bytes over time. If the size keeps increasing, then this could be an indication of a memory leak.
Check Operating System: It is also possible that the operating system may be the source of the error. For example, some older versions of Windows such as XP and Vista may have a memory limit that is too low for the program to run properly. If this is the case, then it is recommended to update the system to the latest version.
FAQ
What Is Virtual Memory?
Virtual memory is a term used to describe the amount of RAM (Random Access Memory) and hard drive space that is available to programs on a computer.
What Causes the “forrtl:severe (41): insufficient virtual memory” Error?
There are a few different causes for the “forrtl:severe (41): insufficient virtual memory” error, including insufficient disk space, large memory limit being set, and memory leaks.
How Can I Prevent the “forrtl:severe (41): insufficient virtual memory” Error?
The best way to prevent the “forrtl:severe (41): insufficient virtual memory” error is to regularly check the amount of memory available on the system, the program use of memory, and the system’s hard drive space. It is also important to check for memory leaks and to update the operating system to the latest version.
What Is the Best Way to Resolve the Error?
The best way to resolve the “forrtl:severe (41): insufficient virtual memory” error is to check the amount of memory available on the system, the program use of memory, and the system’s hard drive space. It is also important to check for memory leaks and to update the operating system to the latest version.
Are There Any Other Steps I Can Take to Resolve the Error?
Yes, there are some other steps that can be taken to resolve the “forrtl:severe (41): insufficient virtual memory” error. These include reducing the memory limit for the program, releasing unused memory, and checking the operating system for out of date software.
Conclusion
The ‘forrtl: severe (41): insufficient virtual memory’ error should not be a cause for worry as it can be easily solved by following the above-mentioned instructions. If the problem persists, it is best to contact a technical support expert for further assistance.
