Sometimes getting messaging.adaptors.http.UnexpectedEOF with http target

i have 3 target endpoints in my proxy with connections defined like this:

    <HTTPTargetConnection>
        <Properties/>
        <LoadBalancer>
            <Algorithm>RoundRobin</Algorithm>
            <Server name="core-api-01"/>
            <Server name="core-api-02"/>
            <Server name="core-api-03"/>
        </LoadBalancer>
        <Path>/services/user/validateMemword</Path>
    </HTTPTargetConnection>

core-api-* servers defined with port 80 - http

as soon as the error in not regular, I can't trace it and understand where and why it happened.

how it's possible to understand the exact point, where, and why error appeared?

is it possible to get more details on this error like:

- target endpoint name

- exact server from target endpoint

- the realistic message. why it decided that EOF was unexpected?

Regards.
