Hi,
I have a Custom GP Service written in JAVA and published as GPService in asynchronous mode in ArcGIS Server 10.7.1. I use it to find version differences for a feature class by providing the global ids of features. When there are huge number of records, I hit the service in batches of 1000 records. This work when the record count is low. But when I hit the service continuously for more than 80k records in batches of 100 (which is total of 80+ different requests continuously), I am getting below error in the ArcGIS Server logs.
com.esri.arcgis.discovery.json.JSONException: Expected a ':' after a key at character 38 of {002FAFF3-E3C1-4D45-848A-2F26BDD58025},{002FB64A-D639-448A-9BA9-BE729FE5122B},....<list of GUIDs continue> at com.esri.arcgis.discovery.json.JSONTokener.syntaxError(JSONTokener.java:454) at com.esri.arcgis.discovery.json.JSONObject.<init>(JSONObject.java:199) at com.esri.arcgis.discovery.json.JSONObject.<init>(JSONObject.java:273) at com.esri.rf.util.RUtil.toJsonValue(RUtil.java:410) at com.esri.rf.util.RUtil.paramsToJson(RUtil.java:368) at com.esri.rf.RRequest.paramsToJson(RRequest.java:1070) at com.esri.client.app.templates.OperationTemplate.gatherParams(OperationTemplate.java:314) at com.esri.client.app.templates.OperationTemplate.execute(OperationTemplate.java:108) at com.esri.client.app.gpserver.GPTaskHandler.submitJob(GPTaskHandler.java:133) at com.esri.client.app.gpserver.GPTaskHandler.service(GPTaskHandler.java:68) at com.esri.rf.RServlet.service(RServlet.java:123) at javax.servlet.http.HttpServlet.service(HttpServlet.java:741) at org.apache.catalina.core.ApplicationFilterChain.internalDoFilter(ApplicationFilterChain.java:231) at org.apache.catalina.core.ApplicationFilterChain.doFilter(ApplicationFilterChain.java:166) at org.apache.tomcat.websocket.server.WsFilter.doFilter(WsFilter.java:53) at org.apache.catalina.core.ApplicationFilterChain.internalDoFilter(ApplicationFilterChain.java:193) at org.apache.catalina.core.ApplicationFilterChain.doFilter(ApplicationFilterChain.java:166) at org.apache.catalina.filters.HttpHeaderSecurityFilter.doFilter(HttpHeaderSecurityFilter.java:126) at org.apache.catalina.core.ApplicationFilterChain.internalDoFilter(ApplicationFilterChain.java:193) at org.apache.catalina.core.ApplicationFilterChain.doFilter(ApplicationFilterChain.java:166) at org.apache.catalina.core.StandardWrapperValve.invoke(StandardWrapperValve.java:200) at org.apache.catalina.core.StandardContextValve.invoke(StandardContextValve.java:96) at org.apache.catalina.authenticator.AuthenticatorBase.invoke(AuthenticatorBase.java:490) at org.apache.catalina.core.StandardHostValve.invoke(StandardHostValve.java:139) at org.apache.catalina.valves.ErrorReportValve.invoke(ErrorReportValve.java:92) at org.apache.catalina.core.StandardEngineValve.invoke(StandardEngineValve.java:74) at org.apache.catalina.connector.CoyoteAdapter.service(CoyoteAdapter.java:343) at org.apache.coyote.http11.Http11Processor.service(Http11Processor.java:408) at org.apache.coyote.AbstractProcessorLight.process(AbstractProcessorLight.java:66) at org.apache.coyote.AbstractProtocol$ConnectionHandler.process(AbstractProtocol.java:834) at org.apache.tomcat.util.net.NioEndpoint$SocketProcessor.doRun(NioEndpoint.java:1415) at org.apache.tomcat.util.net.SocketProcessorBase.run(SocketProcessorBase.java:49) at java.base/java.util.concurrent.ThreadPoolExecutor.runWorker(Unknown Source) at java.base/java.util.concurrent.ThreadPoolExecutor$Worker.run(Unknown Source) at org.apache.tomcat.util.threads.TaskThread$WrappingRunnable.run(TaskThread.java:61) at java.base/java.lang.Thread.run(Unknown Source)
I can infer from above that there is some issue when the GP Service is trying to parse input or output data to JSON. I need help as to what the reason can be and possible solution.
Thanks,
