Jave Heap Space Error

LorneDmitruk — Thu, 16 Aug 2012 14:41:25 GMT

I've been running into the following problem with a map service. The service works file when accessed through ArcMap, ArcCatalog and the services directory. However when I use the service in a Flex application built with the Flex Viewer The service does not draw and registers a failure in the log files. The following is what's recorded in the log file:

SEVERE Aug 16, 2012 9:26:42 AM Internal Server Error. Error handling service request: java.lang.OutOfMemoryError: Java heap space Rest
SEVERE Aug 16, 2012 9:26:42 AM Instance of service 'UpTimeData.MapServer' failed to process a request. Server

I'm running on Windows 2003 R2 8 core with 8 GB of ram (I know this should be at least 16 GB). I've tried with the data for service from both an Enterprise GDB and a file GDB with the same results.

Any hints or suggestions on how to deal with this issue.

Cheers!

Just a Question, have you tried to increase the following parameters in the machine-config.xml file (located in ArcGIS_HOME\framework\etc\machine-config.xml) ?

<WebServerMaxHeapSize>-1</WebServerMaxHeapSize>
<AppServerMaxHeapSize>256</AppServerMaxHeapSize>
<SocMaxHeapSize>700</SocMaxHeapSize>
<WebServerMaxHeapSize>-1</WebServerMaxHeapSize>

The handlers (REST, SOAP, OGC, Admin), the token service, and Manager application run in a single process. That process is designed to not use more than 1/4 of the available RAM on the machine. Since you have 8 GB of RAM, then that process won't use more than 2 GB of memory. If it does then it will throw an error message since that is a very unusual situation. We don't provide a means to increase the memory for that process. The settings that Patrice suggested increase memory in the event that you have a Java-based SOE that consumes a large amount of memory but won't help here.

In this case, it's likely that the Flex app is making some call that is returning a huge amount of data (I am guessing 500 MB to 1 GB). That may not be the desired behavior since just downloading that much data will take a while. It's also possible there is a bug, but we ourselves haven't seen this error even under heavy load testing. To really reach a diagnosis we will need you to open a Support incident and we will ask you to do some tests that will help us determine the root cause.

sorry to bring up an old post,

ON 10.2.2, my javaw process is hitting 1/4 of my machine memory (8gb of 32gb) and arcgis server goes out to lunch. Only a manual restart of the arcgis server service brings it back. When this happens, only 22gb of 32gb of ram are in use, so there is plenty of room.

Any guidance?

Thank you. Increasing the SocMaxHeapSize has helped me.
