在AWS Lambda上的分段錯誤

解決方案

解決方案是在PDF文件渲染後調用GC.Collect方法。 已在Amazon Linux 2023上通報此問題，並使用最近的IronPDF版本； 使用.NET 6和Amazon Linux 2的先前部署不受影響。

// Create an instance of ChromePdfRenderer
ChromePdfRenderer renderer = new ChromePdfRenderer();

// Render the HTML string to a PDF document
PdfDocument document = renderer.RenderHtmlAsPdf(htmlString);

// Explicitly trigger garbage collection to help manage memory usage
GC.Collect();

// Create an instance of ChromePdfRenderer
ChromePdfRenderer renderer = new ChromePdfRenderer();

// Render the HTML string to a PDF document
PdfDocument document = renderer.RenderHtmlAsPdf(htmlString);

// Explicitly trigger garbage collection to help manage memory usage
GC.Collect();

' Create an instance of ChromePdfRenderer
Dim renderer As New ChromePdfRenderer()

' Render the HTML string to a PDF document
Dim document As PdfDocument = renderer.RenderHtmlAsPdf(htmlString)

' Explicitly trigger garbage collection to help manage memory usage
GC.Collect()

多進程渲染和wstring_convert::from_bytes錯誤

如果ChromePdfRenderer。 這會產生分段錯誤或C++異常：

Process runtime-1 exited: signal: segmentation fault
Error while generating PDF from HTML: 'wstring_convert::from_bytes'

這些錯誤是間歇性的，可能僅在第一次或第二次Lambda容器調用後出現。

IronPdf.Installation.SingleProcess = true;
IronPdf.Installation.TempFolderPath = "/tmp";

var renderer = new ChromePdfRenderer();
var pdf = await renderer.RenderHtmlAsPdfAsync(htmlString);

IronPdf.Installation.SingleProcess = true;
IronPdf.Installation.TempFolderPath = "/tmp";

var renderer = new ChromePdfRenderer();
var pdf = await renderer.RenderHtmlAsPdfAsync(htmlString);

Imports IronPdf

IronPdf.Installation.SingleProcess = True
IronPdf.Installation.TempFolderPath = "/tmp"

Dim renderer As New ChromePdfRenderer()
Dim pdf = Await renderer.RenderHtmlAsPdfAsync(htmlString)

// Avoid: global renderer reuse
private readonly ChromePdfRenderer _renderer = new();

// Avoid: calling Initialize()
Installation.Initialize();
