Since there are many "Unknown" applications and due to following setting on the firewall, it is hitting daily packet capture limit.

Either app override all the unknown application.
1. Application Override
Or turn it off from the CLI

> configure
# run show running application setting | match "Unknown capture"
  Unknown capture               : on
# set deviceconfig setting application dump-unknown off
# commit
