QNAP Error Code 58 is a warning that your NAS device's system event log is nearly full. When the log fills up completely, older entries are overwritten or new events stop being recorded, which can make it harder to diagnose future problems. Clearing or archiving the log promptly keeps your NAS running smoothly and ensures you don't miss critical system alerts.

  1. Log In to the QNAP Management Interface

    Always use an administrator account when making system changes. Avoid logging in over an unsecured public network.

When to Call a Professional

Contact QNAP support or a qualified IT professional if you are unable to log in to the management interface, if the log cannot be cleared due to a system error, if you notice repeated critical hardware warnings (such as multiple drive failures or overheating alerts) in the exported log, or if Error Code 58 returns very quickly after clearing, which could indicate a runaway process flooding the log with events.

Frequently Asked Questions

Is QNAP Error Code 58 dangerous or urgent?
Error Code 58 is a medium-severity warning, not an emergency. It means your system event log is nearly full and new events may stop being recorded or old ones may be overwritten. It will not immediately cause data loss, but you should clear the log soon so your NAS can continue tracking important system events properly.
Will clearing the system log delete any of my files or data?
No. The system event log only contains records of events and notifications generated by the NAS operating system. Clearing the log has no effect whatsoever on your stored files, folders, backups, or any data saved on the drives.
Why does the QNAP event log fill up so quickly?
The log can fill up quickly if the NAS is generating a high volume of events, such as repeated failed login attempts (a sign of brute-force attacks), frequent drive read/write errors, recurring application crashes, or a misconfigured service that logs every action. Review the exported log to identify and address the root cause.
How do I stop Error Code 58 from coming back?
Enable automatic log rotation in the System Logs settings so the NAS clears or archives old entries on a schedule automatically. Also set up notification alerts so you are warned early when the log is getting large. Addressing any underlying issues that are generating excessive log entries will also help keep log size under control.
Can I access QNAP system logs remotely to fix this error?
Yes. If you have QNAP's myQNAPcloud or VPN remote access configured, you can log in to the QTS management interface from anywhere and clear the system log remotely just as you would on a local network. Make sure your remote access is properly secured with strong passwords and two-factor authentication.
