The error appears randomly with no stack trace that relates to our code. I googled the APR codes but could not make sense on how to interpret this error accordingly. It is always -730054. Can anyone shed the light on what it could possibly mean?

Answer 1

Here's a compelling explanation that I cannot prove:

730054 = 720000 (Tomcat APR_OS_START_SYSERR) + 10054 (WSAECONNRESET)

In other words, connection reset by peer, so the client dropped the connection and there's nothing to do on the server side about it.
