VSP-MEMORY COMPATIBILITY FOR RTM (LINUX)
In Linux systems, if the RTM feature is enabled, VSP-Memory may not function as expected. This is defined by the environment variable glibc.elision.enable. This is a global setting at the Operating System level. The setting is dependent on the below factors:
-
Operating System and version
-
glibc library version
