Raspberry pi misses the time frame

[dreamboatcap]

Hey there,

I've been struggling with this at least a month. Please help me. My farm misses the 25 seconds time frame for uploading proofs. It all starts with "Don't have rc hash #####. caching sinage point ##" info message. Then this message keeps coming at least 3 or 4 times. When the proof is ready to be sent, it's missing the time frame and pool sends a too_late error. This is happening at least 20 times a day.

I tried connecting my base machine and raspberry pi to the same network simultaneously. Base machine didn't miss any time frame while the raspberry pi missed 5-6 times per hour. I tried overclocking pi and the problem persisted. Then i tried keeping wallet db and blockchain db on different external hard drives in case the problem is caused by hdd speed. Not solved the issue.

I am farming on a Raspberry pi 4 8GB Ubuntu server 20.04. Here's my debug.log.

what kind of drive was the external ? HDD or SSD ?
low perfoming HDD could still be an issue, if the CPU has to wait for IO responses while trying to validate the latest block

[dreamboatcap]

I forgot to update. The problem was indeed on hdd which stores up the blockchain and wallet db. I changed to sdd and the problem is solved.

thank you for providing feedback on the issue!
