Q: When accessing REST services or WFS services, why does the error code 500 appear and the message "Warn: Java heap space" show in the log?
A: As to certain services, the memory is not enough. To solve the problem, use 64-bit iServer, or modify the Java virtual machine memory in catalina.sh/bat in bin directory, and add "-Xmx1024" to JAVA_OPTS, then restart SuperMap iServer.
