Issue/Introduction

SAP Agent crashes when running multiple jobs that perform R3_IMPORT_CALENDAR to update some Calendar Objects.

The last lines of the Agent log contain the following messages:

U00029000 Report '1529478401' for file '/sap_agent/temp/agent_name/PLOG_OEYSZBLQ.TXT' has been started.
U02004202 Create new API connection with client 'XXX' and user 'USERNAME'.

As a result, the job remains in Active status and when displaying the Job's Report, the last line shows the R3_IMPORT_CALENDAR function being called.

Additionally, a log file called  hs_err_pidXXX.log contains the reason for the crash:

# There is insufficient memory for the Java Runtime Environment to continue.
# Native memory allocation (mmap) failed to map 150994944 bytes for committing reserved memory.

...

#  Out of Memory Error (os_linux.cpp:2627), pid=517, tid=0x00007fded5fff700

Environment

Release : 12.x

Component : AUTOMATION ENGINE

Subcomponent: Agent SAP

Cause

The agent sap JVM crashes due to the fact that it reaches the maximum amount of allowed memory (xmx setting):

U02000110 Maximum Heap Memory: '910' MB

Resolution

Increase the Agent SAP xmx parameter to a higher value such as  -Xmx2048M
