Describe the results you expected:
no errors to run,corret to connect
Additional information you deem important (e.g. issue happens only occasionally):
two computer in the same LAN, one computer has this log, other computer was ok(no error logs).
@keyoti commented on GitHub (Dec 20, 2019):
In linux, open sockets equate to open files. Linux has quotas for the number of open files allowed for a user, so you need to increase it (I believe the default is typically 1024)
