WOW!!! I have been dealing with this same issue for several weeks now the solution you found fixed my problem as well! I had to set this value to 10,000 as well. Thanks Jesus & Cindy.

We were on MT 7.5.3. It took almost two months to talk to a US based engineer and get the proper support. They had me do a number of things: - Patch the mid-tier to 7.5.7, - Decrease perm size to 128 and max to 256 (I had it 256m -512m) - Turned on persistent caching, this caused some instability so I turned it off - set the following in Tomcat's configuration page under the Java options tab: -XX:+HeapDumpOnOutOfMemoryError - there was a setting in the mid-tier config.properties files that is set incorrectly out of the box and has to do with ecache: arsystem.ehcache.referenceMaxElementsInMemoryWeight.formFields=28.577. It should be set to 8.577 After all of this, we still had crashes every Monday and Wednesday mornings. In the end, drum roll please, it was the AR Server Administration setting for "Max Entries Returned by Getlist" in the Server Information\configuration tab. It was set for 0, which would allow a user to do a search on the mid-tier that would allow thousands of rows to be returned. It turned out that some users would do a search on Asset Management and would request 20000 - 60000 rows and consume 450mb of heap space in Java. Since we are setting our heap space to 1024 and our server runs at an average of 700mb, the 450mb query would cause the java heap errors. I set maximum on Getlist to 1000 rows, but this caused AR System to start crashing. So, I bumped it up to 10000 rows and it seems to be working okay and Tomcat has not crashed in a week. Check on the Max Entries Returned by Getlist and see if that helps. I ask this to the other admins, what is the happy medium for Getlist that will not cause AR System to crash? I am still going through trial and error, but 10000 rows seem to be a okay for now. ________________________________ From: Action Request System discussion list(ARSList) [mailto:arslist@ARSLIST.ORG] On Behalf Of Michele Mizell Sent: Monday, July 25, 2011 10:22 AM To: arslist@ARSLIST.ORG Subject: java.lang.OutOfMemoryError: Java heap space. All, We are intermittently receiving "java.lang.OutOfMemoryError: Java heap space" in our midtier logs. We have 2 Load Balanced servers which are running Apache Tomcat 5.5.28 and IIS 6. Our min and max memory pool for Java is set to 1024 per BMC's recommendation. These are dedicated servers : Windows 2003 Standard x64 Edition SP2 Our heap memory is constantly maxed out. Has anyone experienced this error in your environment? BMC support has not been helpful in determining the cause and solution.
