EDIT: api message is LcpItfPairGet. Hi Pim, govpp (go) is used for API communication. I have just discovered a way how to reproduce an issue in my home environment. Test utility can be hound at github (also with precompiled binary ... I know, I know ... ). https://github.com/petrbol/govppApiLcpTest/tree/master vppctl create loopback interface instance 101 > vppctl create loopback interface instance 102 > vppctl create loopback interface instance 103 > vppctl create loopback interface instance 104 > vppctl create loopback interface instance 105 > > vppctl lcp create loop100 host-if loop100 > vppctl lcp create loop101 host-if loop101 > vppctl lcp create loop102 host-if loop102 > vppctl lcp create loop103 host-if loop103 > vppctl lcp create loop104 host-if loop104 > vppctl lcp create loop105 host-if loop105 > > How to reproduce: 1. systemctl restart myVppService 2. add commands upper 3. ./govppLcpDumpTest (a few pass, the test will be failed) Now, the interesting thinks ... 4. vppctl show interface 5. ./govppLcpDumpTest (test will PASS for 100% for me) Regards Petr pá 15. 4. 2022 v 22:40 odesílatel Pim van Pelt <p...@ipng.nl> napsal: > Hoi Petr, > > I do not observe this with linux-cp or lcpng on Python API, after > doing O(10k) lcp_itf_pair_get() calls.
