  • lsof komutu kitaplığı DEL durumunda gösterir:
[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

Kitaplık, normal kitaplığın yüklemesini önleyen bir DEL durumundadır (eski kitaplık dosyası tanımlayıcısı). bu nedenle hata "zaten başka bir sınıf yükleyicide yüklü" hatasını gösterir.

Resolution

(1) Belleği boşaltmak/yeniden yüklemek için sunucu yeniden başlatıldı: NetWorker RESTAPI, "Native Library /nsr/authc/webapps/nwrestapi/WEB-INF/lib/librestapi64.so alreadyloaded in another classloader"
hatasıyla yüklenemiyor(2) Emcauthctomcat.cer dosyasını Java cacerts anahtar deposuna aktardı: NetWorker: Cacerts anahtar deposundan kaldırılan NetWorker REST API emcauthctomcat sertifikası
