Hi vpp-dev, I'm running a C program which adds/removes interfaces, IPs, routes, etc. to VPP via the C API, along with a Python test suite which checks the results of the first program multiple times by querying VPP using the Python bindings.
I'm seeing a fairly reproductible issue (when repeating the test suite a number of times), where the VPP API thread remains blocked, always after the clib_mem_free of a ip_route_details reply message (response to Python). Traces: * This is VPP 19.08 with slight plugin changes; I can provide the packages if needed. * The backtrace is here: https://gist.github.com/SCadilhac/bb9ca9600d757b13726e05ae34923c1a#file-backtrace * The startup config file is here: https://gist.github.com/SCadilhac/bb9ca9600d757b13726e05ae34923c1a#file-startup-conf * I don't know how to extract the API dump, as the CLI gets unresponsive, and the process /tmp/api_post_mortem file remains unwritten. * The gzipped core dump is here: http://www.netfishers.onl/downloads/core.24542.gz Any help is welcome :-). Is there anything I'm obviously doing wrong? I'm happy to open a Jira issue if this can help. Thanks, Sylvain
