I'm experiencing many "Socket accept failed: The specified network
name is no longer available." exceptions in the Tomcat error log.
These exceptions happen both on port 80 and 443. Both connectors are
using Http11Nio2Protocol.
I can't reproduce this exception on the local PC, but on the
production instance it happens ~1500 times every day.
Please help me to understand what is the cause of them.
System details:
Windows Server 2012 R2
AWS c4.2xlarge instance
Tomcat 9.0.6
Oracle JRE 1.8.0_162-b12
