Partial file transfer using SCP

Hi everyone,

I am using SCP to to upload file to a router, I noticed that intermittently, sometimes file transfer to the device is a partial but SCP claims to be successful. when last time I faced this problem, I added a delay of 5ms in subsequent packet transfer. It worked well for months and I started seeing this issue again. Most of the time last packet is dropped or missed. Below are some application logs:

Scp connection succeeded
Sending SCP Path without Quotes
SCP data packet send delay : 5.
Source stream length 86763.
Total data send 16384. Last data read 16384.

Total data send 81920. Last data read 16384.
Total data send 86763. Last data read 4843.
Uploading finished. Total uploaded 86763

File size on device : 83815

Is this a known problem already?

Non sono identificati file sorgente né test. Inizia riproducendo il caricamento SCP su un router usando il trasferimento segnalato di 86,763 byte e confronta la dimensione ricevuta con i log del client; è completato quando il file completo arriva in modo affidabile e il trasferimento non segnala il successo per un file parziale.
