1、关阀分析返回{"succeed":false,"error":{"code":400,"errorMsg":"没有初始化。"}}。
编辑文件D:\SuperMap\SuperMapiServer11i\webapps\iserver\WEB-INF\iserver-services.xml，将对应服务的initFacilityAnalyst改为true，添加directionField为正确的流向字段Direction即可。
<provider class="com.supermap.services.providers.UGCTransportationAnalystProvider" enabled="true" name="transportationAnalyst-Network_database">
<config class="com.supermap.services.providers.TransportationAnalystSetting">
<workspaceConnectString>D:/SuperMap/Data/项目/Network_database.smwu</workspaceConnectString>

<edgeIDField>SmEdgeID</edgeIDField>

2、两个图层，坐标系和投影都相同，但是iServer空间查询，一个可以查出数据，另一个图层无法查出数据。
2023-09-25 09:15:48 [error] 获取记录数失败, ThreadID: , Timespan(ms): 0, ResourceID: ELc082, SourceCode: ()
2023-09-25 09:15:48 [error] 第 1 行, 第 1122 列[.1]附近出现错误:

在SuperMap iDesktop数据源中，复制无法查出数据的数据集，删除原来的数据集，将复制的数据集改为原来的名字即可。
3、iServer有的图层无法添加点要素。
2023-09-25 10:10:17 [error] 数据集[GasFaMen]提交数据失败, ThreadID: , Timespan(ms): 0, ResourceID: ELe068, SourceCode: ()

4、rest api接口报错：geometry已经被释放。
日志文件\supermap-iserver-11.0.1-windows-x64\support\objectsjava\bin\log\iObjects.2023.10.13.log中的错误：

解决方法：重启iServer。
5、iDesktop新建数据库型数据源，DMPlus为灰色。

6、空间查询线图层能查出数据，点图层无法查出数据。
空间索引错乱问题。右键数据表，选择重建空间索引，重新计算范围。
7、获取图标报错：图片http:~/~/192.168.11.6:3090/iserver/output/resources/Distribution/SYMBOLMARKER/922691_861310927.png不可读。
参考文档：
8、添加要素报错：the number of 'fieldNames' and 'fieldValues' are not equal。
日期DATETIME字段要传yyyy-MM-dd格式，不要传时间戳。
9、查询要素返回：{"succeed":false,"error":{"code":400,"errorMsg":"对象已经被释放"}}。
重启iServer解决。
10、iServer报错：Java.lang.OutOfMemoryError: Java heap space.
编辑SuperMapiServer11i\bin\catalina.bat，查找set JAVA_OPTS一行，改为以下配置即可。
set JAVA_OPTS=%JAVA_OPTS% -Xms512m -Xmx8096m -Xss512k
11、iServer管理页面，点击服务管理报错：java.lang.ClassCastException: com.supermap.server.impl.DefaultServicesContainer cannot be cast to com.supermap.server.impl.LazySBMDecorator。
重启iServer解决。
