During sudden burst of traffic, the TCP fifo gets full. When this happens the openssl TLS app de-schedules the transport. But once the TCP data is sent out, the TLS is not resuming. VPP ends up in a state where TCP fifo is empty, but the TLS fifo is full and no more Tx happens on TLS fifo.
VPP version: 21.01 We came across this commit - session tls: deq notifications for custom tx ( https://github.com/FDio/vpp/commit/1e6a0f64653c8142fa7032aba127ab4894bafc3c ) Not sure what is the issue fixed by this commit, but It doesn't seem to fix the above mentioned issue.
