Pinned topic Performance issue and out-of-memory problem

‏2013-02-27T08:04:49Z |
We use Mashup Center 3.0.0.1. Our mainly work on Mashup Center is doing "data mashup" to combine and filter multiple data source to one ATOM feed. The largest atom feed will be more than 60MB. And we have 130+ feeds already on Mashup Server. We run it in 64-bit linux we modify JVM heap size to 3GB.

This time when I try to create some CSV feeds and upload CSV file, the server was not stable. It always dump javacore files. And I got Out-of-Memory exception in the nativerr.log as below.

Can anybody have a look at it? Thanks.
JVMDUMP006I Processing dump event "systhrow", detail "java/lang/OutOfMemoryError" - please wait.
JVMDUMP032I JVM requested Snap dump using '/opt/IBM/MashupCenter/3.0/mm_profile/Snap.20120816.043250.5641.0010.trc' in response to an event

PS: Mashup Center is now sunset. Does the data mashup ability migrate to other product, such as Portal Server or else?

    In "data mashup", we configure the interval time nearly real time. And JVM heap size over 3.5GB, the mashup center will crash down when start up. Any suggestion will be appreciate. Thanks.

    The server will restore after restarting it. The out of memory problem happens when I select an file to upload and click "Next". After 1-2 feed creates the out-of-memory will happened again. So we have to restart it again and again. It's really painful.
