Cannot start XS Controller

Hi all,

on AWS i set up an EC2 instance where i installed Hana 1.0 with XSA. Last week it works fine. However, yesterday i installed addiotionally an SAP NW frontend server on the same machine. It all works fine. Now i encouter the problem that the Hana DB is not starting up to 100% especially the XS Controller for XSA. During the log files i found out that an out of memory exeception occurs. However, the machine has 40 GB available space. Somebody knows where the problem is.

Best regards,

Manjinder
