Cause
"sysmgr" hizmet çökmesi, MDS sürümleri 8.1(x) ile 8.3(x) arasında çalışan MDS 9148S ve MDS 9250i platformlarında meydana gelir. Çekirdek paniğine neden olur ve anahtarın tamamının kullanılamayabilir. Sonuç olarak, sistemin işlevselliği geri yüklemek için zorla yeniden yüklenmiş olması gerekir. Çekirdek paniği nedeniyle "sysmgr" hizmetinin feshinin tam nedenini belirlemek mümkün değildir.
Resolution
Geçi -ci çözüm:
Bu sorunu azaltmak için bilinen bir geçici çözüm yoktur. Ancak kullanılamaz durumu serbest bırakmak için anahtarı yeniden takın.
Çözünürlük:
TAC'nin önerisi, kodu sürüm 8.4'e (2f) yükseltmektir.
Etkilenen Bilinen Sürümler: 8.3(2)
Cisco Sorun Kimliği: CSCvu16450 ve
