SCTP bind reports "Address already in use" with no active SCTP listening programs

Solution Verified - Updated -

Issue

  • SCTP bind reports "Address already in use" with no active SCTP listening programs
  • sctp_bind results in EADDRINUSE when no active endpoints. The problem seems to only occur when snmpd is running as well.

Environment

  • Red Hat Enterprise Linux 8.2 (kernel-4.18.0-161.el8) and later
  • SCTP (Streaming Control Transmission Protocol) listener application
  • Net-SNMP daemon snmpd running
