Answer 1

我们最近遇到了类似的问题，它与您的报告尝试检索的记录数无关，而是与您使用Crystal Reports运行时打开和访问报告的次数无关，特别是创建并且使用ReportDocument变量，而不关闭和处理它。

看看这篇相关文章：
Crystal Reports Exception: The maximum report processing jobs limit configured by your system administrator has been reached

实际上，我们的解决方案是以下模式：

ReportDocument report = CreateReportDocument(reportPath);

// Do stuff with the report

report.Close();
report.Dispose();
GC.Collect();

这解决了我们在获得相同的异常之前能够生成少量报告的问题。我希望这有帮助！

首先在cmd提示符下发出ISSRESET命令以清除日志，并将以下代码放在报表查看器的Unload事件中。

这是一个例子

Protected Sub CrystalReportViewer1_Unload(ByVal sender As Object, ByVal e As System.EventArgs) Handles CrystalReportViewer1.Unload
        master1.Close()
        master1.Dispose()
        GC.Collect()
    End Sub
