Hi Nunberg,
My libcouchbase-dev is 2.3.2. I have tried to use your
libcouchbase-dev 2.4.0, but situation even be much worsen.A lot "*timeout*"
were throw out,but no *"src/server.c:666:
lcb_server_purge_implicit_responses: Assertion `c->cmd_log.nbytes' failed."*
errors. Now I am sure that the error " *src/server.c:666:
lcb_server_purge_implicit_responses: Assertion `c->cmd_log.nbytes' failed.*"
makes my python application container(uwsgi) down before. By the way some
time another error *"evmap.c:401: Assertion ctx failed in evmap_io_active*",
So really need your help.
Best regards.
