Hi @Olivia Dunham<mailto:theoliviadun...@gmail.com>, Recently I met the exact same issue, TLS TX svm fifo gets full after burst of traffic and it will never resume, meanwhile, TCP TX svm fifo is empty at that time I’m using VPP20.09, I believe there is some issue in TLS layer, so did you fix the issue later? If yes, can you share the solution.
BRs, Kevin From: vpp-dev@lists.fd.io <vpp-dev@lists.fd.io> On Behalf Of Olivia Dunham Sent: Tuesday, September 14, 2021 8:58 PM To: vpp-dev@lists.fd.io Subject: [E] COMMERCIAL BULK: [vpp-dev] TLS app stuck after burst of traffic #vpp-hoststack Email is from a Free Mail Service (Gmail/Yahoo/Hotmail….) : Beware of Phishing Scams, Report questionable emails to s...@mavenir.com<mailto:s...@mavenir.com> 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. ________________________________ This e-mail message may contain confidential or proprietary information of Mavenir Systems, Inc. or its affiliates and is intended solely for the use of the intended recipient(s).
