+#### Q: 操作中遇到 "java.lang.OutOfMemoryError: Java heap space" 报错?
+A: Defold 编辑器基于 Java, 所以某种情况下可能会造成内存不足. 可以尝试手动编辑配置文件来增加内存使用量. 配置文件叫做 `config`, 在 macOS 位于 `Defold.app/Contents/Resources/` 文件夹下. 在 Windows 位于 `Defold.exe` 可执行文件同一个文件夹下, 在 Linux 位于 `Defold` 可执行文件同一个文件夹下. 打开 `config` 文件, 在 `vmargs` 后顶头加入 `-Xmx6gb` 参数. 加入 `-Xmx6gb` 的意思是使用 6 GB 内存 (默认 4GB). 如下所示:
+
+```
+vmargs = -Xmx6gb,-Dfile.encoding=UTF-8,-Djna.nosys=true,-Ddefold.launcherpath=${bootstrap.launcherpath},-Ddefold.resourcespath=${bootstrap.resourcespath},-Ddefold.version=${build.version},-Ddefold.editor.sha1=${build.editor_sha1},-Ddefold.engine.sha1=${build.engine_sha1},-Ddefold.buildtime=${build.time},-Ddefold.channel=${build.channel},-Ddefold.archive.domain=${build.archive_domain},-Djava.net.preferIPv4Stack=true,-Dsun.net.client.defaultConnectTimeout=30000,-Dsun.net.client.defaultReadTimeout=30000,-Djogl.texture.notexrect=true,-Dglass.accessible.force=false,--illegal-access=warn,--add-opens=java.base/java.lang=ALL-UNNAMED,--add-opens=java.desktop/sun.awt=ALL-UNNAMED,--add-opens=java.desktop/sun.java2d.opengl=ALL-UNNAMED,--add-opens=java.xml/com.sun.org.apache.xerces.internal.jaxp=ALL-UNNAMED
