Sudden clusters of Channel failed logs

[brezinajn]

Ktor Version and Engine Used (client or server and name)
versions: 1.2.4, 1.2.5
modules: server-netty, jackson, auth, locations

Describe the bug
In seemingly random intervals I'm seeing batches of logs /route-name, channel failed. I've tracked the source of the log to [here].(

ktor/ktor-server/ktor-server-host-common/jvm/src/io/ktor/server/engine/DefaultEnginePipeline.kt

Line 103 in 424d1d2

is ChannelIOException -> log.info("$status: $logString, channel failed")

)
I'm unable to reproduce the behavior on my local machine. That makes me belive it might happen due to high load. Since the message does not offer much insight to what is happening, I'm unable to properly analyse the problem.

To Reproduce
Not sure

Expected behavior
Clear message what is happening.
