Failed due to heavy traffic error

If the number of concurrent connections to download an attachment has exceeded the default value set for your pod, a user may receive an error message stating Failed due to heavy traffic (Figure 1):


Figure 1 Error

The default value is set to 50 connections per node, so depending on your pod this value may be different.

For example, if an attachment is being sent in a large room with 500 users, the first 50 users will be able to view the attachment immediately, but the 51st user viewing the attachment simultaneously will receive the Failed due to heavy traffic error message and a Retry button will be displayed to them (Figure 2):

Note: Depending on the size of the attachment, the user may have to wait a few milliseconds before selecting Retry to download the attachment.

Note: In later versions of Symphony, a timeout between 1 to 20 is defined meaning the user will no longer need to select retry manually to download the attachment.
