Swap Memory Usage Reaching To 100% (Doc ID 2176230.1)

Information in this document applies to any platform.

Symptoms

Endeca Server 7.5.1

The production swap memory increases over time reaching 100%. What is observed is the system is not relinquishing swap memory. This leads a degradation of performance ultimately causing the system to get into a hung state. When this happens, Studio becomes unresponsive. This impacts the users in such a way they cannot use Studio.

This is reproducible if many domains are running. In this case, 60. The memory needed is considerable for each dgraph and it is 6.4*60 = 384GB just for the dgraph cache.
