Try setting "abap/buffersize = 800000" at the instance profile and restart the system.

Have you set the up the SUSE Linux correctly for the SAP installation? Have you set the OS limits and Linux kernel parameters correctly? I would first set the limits to unlimited and also set the relevant Linux kernel parameters and restart the server.

1771258 - Linux: User and system resource limits

You can read the SAP notes specific to Linux distributions in this note. 2369910 - SAP Software on Linux: General information

Also try to set the parameter em/initial_size_MB with a smaller value, let's say to 5 GB to 6 GB ans restart the system and check if it fixes tthe problem.

Looks like you have some memory problems. How much RAM do you have on your server?
