what means this logs?

[bund]

Hello.

Does anyone know what this log means?

I create a prevent log as the anti-virus works, and the content looks like 'failed writing the file'.

What means 'Failed writing the file'?

Why is this happening?

Is the gateway experiencing high load and which version is the gateway deployed with?

There are a few possible causes for this symptom that might be best reviewed with TAC.

Otherwise I'd probably start with exploring HCP reports and addressing any performance or capacity oriented issues flagged there.
