每次调用某个模板时，为什么ColdFusion会崩溃/重新启动？

Question

我支持在Windows Server 2003 R2上运行的ColdFusion 8网站（应用了所有Windows安全更新）。该网站平稳运行99.9％的时间。但是，大约2个月前，ColdFusion 8 Application Server服务每晚晚上10:30开始崩溃并重新启动。有一个ColdFusion计划任务每​​晚晚上10:30运行，因此我尝试手动运行它（直接在浏览器中访问URL），并确信ColdFusion 8 Application Server服务崩溃并重新启动。所以，显然这是导致这种情况发生的一个模板。

这个模板的功能是读取一个充满PDF文件的目录，然后遍历这些文件为每个使用CFPDF创建几个缩略图。此计划任务已运行多年，未出现此问题。在处理单个文件之前，CF服务几乎立即出现崩溃/重新启动。

我试着在我们的Staging环境中运行相同的模板，并且运行正常 - 没有CF重启。我很困惑。

通过ColdFusion日志搜索，没有发现任何东西。

感谢@MarkAKruger将我指向CFROOT \ runtime \ bin \ hs_err_pid * .log文件。它看起来像试图将PDF格式为PNG转换时内存问题....

这里是从我最后一次尝试运行此模板（到大，包括在这里），该文件的内容的链接：

Error Dump File

我还是非常感谢所有帮助搞清楚如何解决.....

您可以在/运行/ bin目录下看看，看看，如果你甲肝esome错误文件 - 类似hserrorxxxx .log（不记得java 1.4的格式）。这是一个“热点”错误 - 通常在崩溃时产生。打开一个，看看。我的猜测是你的内存不足，或者在你的PDF中嵌入了一个RGB图像，这会影响你的服务器。您可能能够从hs（hotspot）错误文件中的堆栈中找出它。
