Arcgis server JAVA application every morning problem

[krystian4421]

Hello,

I've developed web application in JAVA API. Since then (maybe 3-4weeks) every morning when someone try to connect to my application always get errors, and then map is not loading. Tomcat log file I always get error like this:

SEVERE: Unable to initialize resource 'ags1'. This resource will be removed
com.esri.adf.web.ags.ADFAGSException: Cannot create MapServer instance for server object 'map1' [hosts=[xxx.xxx.xxx.xxx]]

it's funny because after few minutes when the application is refreshed everything is OK. I dont know what can be a problem. For all day long application is just fine, but everyday the error occurs. I would like to mention, that my tomcat server (v.6) is on VMware and ArcGIS server is on other machine.
can someone resolve my problem?

Hi, Have you checked the health condition of arcgis server and services before you get this error?

http://<<machinename>>:8399/arcgis/rest/services
http://<<machinename>>:8099/arcgismanager/main/login.jsf

may be an issue in the tomcat configuration,
