Ethereum: Discovering the mystery of BSOD on Windows 7
As a developer who works with Blockchain in Noda.JS, it is not uncommon to encounter problems related to memory management and resource distribution. In this article, we will enter the code clip that led to Bluescreen “Bad_Pool_Caller” to Windows 7 and explore why this part of the code creates problems.
Code Code
Here is the code clip in question:
`Javascript
Const Web3 = required (‘web3’);
// Create a new instance of Ethereum
Const Web3 = New Web3 (new web
‘
));
`
Problem
After analyzing this code, it is obvious that an instance ofWeb3 ‘tries to create a connection of HTTP Live Network Service Ethereum. However, this procedure involves calling “Createhyperspace ()” a function on the provider’s facility, which in turn tries to assign memory for a set of Web3 services providers.
Problem
The problem arises when it is called Web3createPool ()
Method because it tries to create a HTTP pool using a previously created instance of a service provider. This leads to the leakage of memory and then causes Bluescreen “Bad_Pool_Caller” in Windows 7.
Why the code causes bsods
When the code clip tries to assign the pool memory, noda.js throws a mistake because memory is already used by other processes. Especially:
- The
Web3createPool () method ()
tries to create a new pool by using a previously created instance of services provider (New Web3 PROVIDERS.HTTPPROVIDER (...)
).
- However, an instance of a service provider is still used elsewhere in the program (probably as an HTTP client or other resource).
Solutions
To solve this problem, you can try the following:
- Make a separate procedure for each Ethereum network : You can create a new procedure for each living Ethereum network using
process.execpath = '/Path/do/noda';
, then forward the instance of a service provider to that process.
`Javascript
Const Web3 = required (‘web3’);
// Create a new http pool connection in a separate procedure
Const Execpaath = ‘C: \\ software files \\ node.js \\ node.exe’;
Const ProjectDir = __Dirname;
process.execpath = $ {Projectdir}/$ {execpath}
;
New Web3providers.httpprovider (
‘
) .CreatePool ((error, pool) => {
Console.log (pool);
});
`
- Use a different method to create an HTTP service : Instead of usingweb3createhyperspace ()
, then creating an HTTP service provider, you can use
web3provs.httpproviderKonstruktor directly with the Ethereum network network.
Javascript
Const Web3 = required (‘web3’);
Const Provider = new web
‘
);
// Create a new instance of Ethereum
Const Web3 = New Web3 (Provider);

Conclusion
Bluescreen “Bad_pool_caller” on Windows 7 can be caused by memory leaks in blockchaini developed with noda.JS. Understanding the clips of the code that creates problems, the developers seem to take steps to solve this problem and create a more robust blockchain application. Remember to always create separate processes or use alternative methods to avoid memory leakage and prevent BSOD.

Keep in mind that Microsoft does not support the creation of a live Ethereum network on Windows 7 and can be subject to change. Always check the compatibility of your application before arranging it in the production environment.
