Symptoms

When first starting up, Essbase applications start successfully. After a while, application startups fail and receive an error in the Essbase web: [Failed to activate lightweight process.]. The same error happens when trying to do an adhoc analysis in Smart View, where Essbase should start the application.

The apsserver log has the following:

Essbase Error(1244022): Application <appname> must be loaded
Cannot load/start olap application. Essbase Error(1200448): [Failed to activate lightweight process.]

The jagent.log has the following:

[2023-06-27T21:51:18.339+00:00] [essbase_server1] [ERROR] [] [oracle.JAGENT] [tid: 210] [userId: <anonymous>] [ecid: 81ccb91c-188d-4ce2-bb52-78b024e6992f-0000000b,0:875:16] [APP: ESSBASE] [partition-name: DOMAIN] [tenant-name: GLOBAL] [SRC_CLASS: oracle.epm.jagent.core.application.ApplicationPOJO] [SRC_METHOD: startApplication] error.starting.application[[oracle.epm.jagent.process.context.EssbaseProcessContextException: lightweight.process.activation.failed

java.io.IOException: Cannot run program "/u01/Oracle/Middleware/essbase/products/Essbase/EssbaseServer/bin/ESSSVR": error=38, Function not implemented
java.io.IOException: error=38, Function not implemented

Once these errors start, no applications will start and a restart will be necessary until the error recurs and then another restart will be necessary.
