Imperva Cyber Community

Hi Imperva Community,

I'm facing an issue with our Gateway where the following critical alarm keeps appearing repeatedly:
"Gateway failed to write violation(alert) event to disk."

The detailed message states:

• The Gateway's disk is full.

• There may be a permissions problem with the file.

• Check the file's write permission.

• Contact Imperva support.

Even after performing some checks, the alarm continues to appear over and over again.

Has anyone experienced a similar issue?

• How can I accurately identify the root cause (disk space issue, file permission problem, or something else)?

• Are there best practices for cleaning up old logs/data on the Gateway to prevent this?

• Should this be escalated directly to Imperva Support, or can it be resolved with regular maintenance steps?

Any guidance or shared experience would be greatly appreciated.

Thanks in advance 🙏

Hi @Bagus Dwi Prasetyo

I had the same issue days ago

And support said, the problem is that the Gateway has reached Peak overload capacity

And you need to validate what kind of traffic cause this issue and create and Agent Monitoring Rule to exclude this traffic to reduce the exceeded traffic

Hi Alejandro Hernandez,

Thank you very much for helping answer my question earlier. I will try to reduce it by adjusting the agent monitoring rule to avoid overload.

However, I would like to validate this alarm. Based on the alarm details provided, the information indicates an issue related to the disk (either full or permission related). This seems to be contradictory to your previous explanation regarding the information from imperva support, which stated that the root cause was excessive traffic.

Hi Bagus,

I am also facing the same error. I have already increased the disk space and deleted unused files from the Gateway, but the error is still recurring. I have raised a support case, but so far, I haven't received any response from the Imperva Support Team.

If anyone has any ideas or suggestions, please let us know.
