我在Windows环境（作为服务）中运行YouTrack 5.1，并在下面获取OutOfMemory异常。有没有办法在作为服务运行时增加堆大小？

Answer 1

解决方案是运行%your_YouTrack_location%\bin\tomcat6w.exe //ES//YouTrack，这将为tomcat设置打开GUI编辑器，并增加了Java选项卡上的最大内存池设置。

Answer 2

作为服务安装时，YouTrack在Apache Tomcat中运行，因此对于任何Tomcat作为服务安装，答案也是正确的。以下是有关如何在YouTrack中更改root密码的文档：http://confluence.jetbrains.com/display/YTD5/FAQ#FAQ-HowtorestoremyrootpasswordifIrunYouTrackasWindowsservice%3F。 您只需要设置-Xmx1024m，而不是提供-Djetbrains.charisma.restoreRootPassword = true，其中1024是以MB为单位的堆大小。
