Description
This issue is discovered from "log4js-node", The latest version of "log4js-node" has the same issue because of this dependency.
replicate step:
- Download source code of this project.
- Create a 'index.js' file in root of this project.
- Input content in 'index.js' file:
var rollers = require('./lib/index');
var stream = new rollers.RollingFileStream('myfile', 10000, 12, {
compress: true,
});
for (let i = 0; i < 30; i++) {
// console.log(i);
stream.write(getContent());
}
stream.end();
function getContent() {
return `
{
a: {a: 1, b: 2, c: 3, d: 4, e: 5, f: 123321, g: 234432432, h: 31321, i: 23232, j: 23432423432432, k: 1123321},
b: {a: 1, b: 2, c: 3, d: 4, e: 5, f: 123321, g: 234432432, h: 31321, i: 23232, j: 23432423432432, k: 1123321},
c: {a: 1, b: 2, c: 3, d: 4, e: 5, f: 123321, g: 234432432, h: 31321, i: 23232, j: 23432423432432, k: 1123321},
......... // 70000 lines repeated
}`
}
- Execute
node index.js
in terminal. - Open the hot file "myfile" with notebook or VSCode as you like. This step is very important. The issue will not replicate without this step.
- Execute
node index.js
in terminal again. If no error occur, you can execute more times. The probability is very high, more than 50%.
Finally get this error in terminal:
