  • NetBackup NDMP 备份因错误“Write to socket failed”而失败。
  • Interrupted system callWrite to socket failed检测到 "" 和 ""/mroot/etc/log/backup


<VOLUME_PATH> Phase_change (IV)
<VOLUME_PATH>  Log_msg (Write DIRNET for BKP ID=<ID>, type=3 interrupted while at waiting for max inflight. Error = Interrupted system call.)
