3296543 - Inexpensive queries fail with composite OOM on SAP HANA DB

Symptom

Queries get terminated with an out of memory error, for example: 4: cannot allocate enough memory

This can also generate a composite out of memory dump <service>_<host>.<port>.rtedump.<timestamp>.compositelimit_oom.trc

When checking the statistics (e.g. OOM trace or M_OUT_OF_MEMORY_EVENTS), you can see that the query actually allocated less than the defined statement allocation limit.
