  • lsof-kommandoen viser biblioteket i deltilstand:
[root@nw_server ~]#  lsof | grep librestapi64
jsvc       4543 nsrtomcat  DEL       REG              253,2   14881546   67764661 /nsr/authc/webapps/nwrestapi/WEB-INF/lib/librestapi64.so

Cause

Biblioteket er i en DEL-tilstand (foreldet bibliotekfilbeskrivelse) som hindrer at det vanlige biblioteket lastes inn. dermed viser feilen «allerede lastet inn i en annen klasselaster».

Resolution

(1) Startet serveren på nytt for å tømme/laste inn minnet på nytt: NetWorker RESTAPI kan ikke lastes inn med "Native Library /nsr/authc/webapps/nwrestapi/WEB-INF/lib/librestapi64.so already loaded in another classloader"
(2) Importert emcauthctomcat.cer til Java cacerts-nøkkellager: NetWorker: NetWorker REST API emcauthctomcat-sertifikat fjernet fra cacerts-nøkkellageret
