其他癥狀包括無法設置ICAP， AVscan 工作失敗、伺服器訊息區塊 （SMB） 緩慢和無法檢視 AVscan 報告。核心檔案可能會放入 /var/crash 資料夾。

Cause

OneFS 9.10 程式碼中出現鎖定問題。

Resolution

OneFS 9.10.1.x、9.11.x 或 9.12.x 沒有因應措施。叢集必須升級至 9.13.x 或更新版本。工程缺陷列為 IME01C-301。切換 AVscan 暫時救濟守護程式：

powerscale1-9# isi services -a isi_avscan_d disable; sleep 30; isi services -a isi_avscan_d enable
