No. ARPs do not consume a [TCP] connection.
It looks like packet 116 is a resend of packet 115, and then packet 117 is the ACK for packet 116. Packet 129 is a resend of packet 112, and then packet 130 is the SYN-ACK for that [second] connection. In both cases, your device seems to be losing a packet and recovering after the resend? How many simultaneous connections does your device support?
Do you have any idea what devices have the "MRVCommu" OUI in their MAC addresses? Maybe those devices are misconfigured?
I haven't had a chance to review the ARP code to see if getting overwhelmed would affect the TCP connections? Regardless, there doesn't appear to be a high enough rate of ARPs to be troublesome. Many of them are 1 second or more apart. Please share any other clues and maybe we can find something... Patrick |
