Overview

You see a sctpCommsUDataReq discard error in the logs, as shown in the image below, and you wish to know what it means. You faced this issue in a standalone SGC.

Information

• This error in the log means that the Linux Kernel SCTP stack returned error when D7 tried to send a message. The error is EWOULDBLOCK, which means association is congested.
  
  
• The number at the end (121 in the image below) refers to the association id.
  
  
  
• The log is printed once at the 1st discarded message, and then for every 256 messages that were discarded (in order not to flood the logs).
  
  
• This process resets when ASPD is restarted.
