TCPIP Errors in GWIA

After we had a GWIA lockup and some mail flow issues, we noticed that we seem to have a lot of TCPIP errors. But I do not know what is a "normal" number of TCPIP errors is?

We are running GW 2014r2 on Linux. We use the GWAVA "cloud" solution as our antispam\antivirus vendor.

At this time the GWIA has been up 5 days and 3 hours:

We have sent 9587 messages and received 30287 messages. There are3368 TCPIP read errors, no TCPIP write errors.

Is this normal?
