Intermittent system unresponsiveness requiring reboot on WordPress droplet

Hello DigitalOcean Support Team,

I am experiencing intermittent issues with one of my droplets hosting a WordPress website, where the system enters an unresponsive state and requires a manual reboot in order to function normally again.

Context:

• Droplet is used solely to host a WordPress website

• From time to time, I observe sudden spikes in CPU (100%) and memory usage

• After these spikes, the system becomes unresponsive (site becomes inaccessible)

• A reboot always restores normal operation

I have already increased the droplet resources once, but I do not believe this is a capacity issue. Under normal conditions, the droplet rarely (if never) exceeds 50% of the allocated CPU and memory.

Request for assistance: I would appreciate your help with:

• Checking whether there are infrastructure-level issues (host node, disk I/O, network, etc.)

• Advising how to better diagnose the root cause of these spikes and freezes

• Recommending monitoring or configuration changes to prevent the system from reaching this unresponsive state

If needed, I can provide:

• Droplet ID (I have only one)

• Approximate timestamps of the incidents (latest was just other day)

• Monitoring screenshots or logs

Thank you in advance for your assistance.

Best regards, Aleksandar Petrov
