Clover Flex: Troubleshooting Low Memory Errors - Solar... | terminalfaults.org

Technical Background:

The Clover Flex uses flash memory for applications, transaction logs, and operating system functions. Insufficient free memory can cause application instability and crashes. Flash memory degradation over time can also contribute to perceived memory issues. External factors like corrupted transaction logs or bloated application cache also impact performance. The device logs errors to flash as well, filling space. System updates can also trigger this if the device is near full capacity.

Symptoms:

Clover Flex displays a 'Low Memory' error message and crashes. Frequency of occurrence is currently unknown.

Possible Causes:

Application cache overload.
Corrupted transaction logs.
Excessive number of installed applications.
Firmware update failure or partial system.
Accumulation of system logs filling the flash memory.
File system corruption on the flash memory.

Solution:

1

Safe Handling: Unplug the Clover Flex from its power source.
2

Restart the device: Press and hold the power button until the device restarts. Observe if the error persists.
3

Clear Application Cache: Navigate to the 'Settings' menu, then 'Apps'. Select each application and clear its cache. Prioritize clearing the cache for frequently used applications.
4

Delete Unused Applications: Uninstall applications that are no longer needed or frequently used to free up memory.
5

Review Transaction Logs: If possible, archive or delete old transaction logs. Access this function through the Clover web dashboard interface and remotely trigger deletion (requires account access).
6

Force a System Update: Navigate to 'Settings' > 'About' > 'System Updates' and check for available updates. Install any pending updates.
7

Factory Reset (Data Loss Warning): As a last resort, perform a factory reset through the settings menu. This will erase all data on the device. Back up critical data via the Clover web dashboard (if possible) before proceeding. Consult Clover support for the correct procedure to ensure PCI compliance. NEVER attempt a hardware reset (via pinholes or internal access).
8

Contact Clover Support: If none of the above steps resolve the issue, contact Clover support for further assistance. Do not attempt any hardware repairs as the device is PCI-PTS compliant and opening the casing will void the warranty and trigger tamper protection.

Safety Warning:

ESD (static electricity) can damage the Clover Flex. Especially in dry environments (winter), ground yourself before handling the device. Ensure the device is unplugged before cleaning. Use a dry, lint-free cloth to clean the touchscreen and exterior. Do not use liquids or abrasive cleaners. Cable strain can cause intermittent power issues; ensure the power cable is properly connected and not under tension. Attempting to open the device will void the warranty and trigger the tamper protection mechanism, rendering the device unusable.

Prevention:

Regularly clear application caches.,Uninstall unused applications.,Monitor the number of stored transactions.,Ensure the device is always running the latest firmware.,Periodically restart the device.,Perform routine maintenance through the Clover dashboard, deleting old logs if possible.

Expert Tip:

If the device is frequently displaying the 'Low Memory' error, consider using the Clover web dashboard to remotely manage application installations and configurations to optimize memory usage across all Clover Flex devices in your fleet. Rebooting the device via the dashboard may also help clear temporary files. The combination of the 'Volume Down' button + Power Button may force a temporary cache clear (check Clover documentation for confirmation, as this can vary by firmware).
