在EMS和Fpolicy.log中发现写入EAGAIN错误

适用场景

• ONTAP 9
• FPolicy
• CIFS
• NFS

问题描述

• 通过多个客户端访问共享时观察到的操作变的很减。
• 启用Fpolicy后无法访问CIFS共享
• EMS或event log show 会报告与EAGAEM错误相关的错误、类似如下所示：

[filer1: fpolicy: fpolicy.eagain.on.write:notice]: Write returned EAGAIN while sending notification to the FPolicy server "12.34.56.78" for vserver ID 3.

• 适用于ONTAP 9.5及更低版本

Fpolicy.log reports errors pertaining to EAGAIN errors similar to the following:
[kern_fpolicy:error:1552] Write returned EAGAIN[35] [0x0x80c408d00] src/fsm/fsm_external_engine.cc:864
