Several alerts daily from our QNAP, please help!

I assumed the role of IT with the company and everything is working fine, but I am looking into all of the alerts we get constantly. They all seem to relate to Seafile. The email alerts come from our QNAP NAS, which hosts the seafile file shares.

I don’t have all of the server information handy, but I do know its a virtual server using esxi and accessed via vmware vsphere. esxi server is at 192.168.2.10, and the seafile vm is 192.168.2.26

Below I will post a couple of the messages, I get several every single day. I hid the domain and file path name
