AuthFailedException: Insert userIpSessionCount to local cache failed

[doublex]

After updating from 3.02 -> 3.1 We have a multi-threaded environment - I don't understand this error message:

Traceback (most recent call last):

This happens with nebula-python 3.0 and nebula-python 3.1 (server always nebula-graph 3.1)

This is what nebula-graphd.dbspace.root.log.ERROR reports:

E20220430 16:53:39.828351 22125 GraphService.cpp:97] Create session for userName: nebulauser, ip: ::ffff:1.2.3.4 failed: Insert userIpSessionCount to local cache failed.

I forgot to mention: We use short living connections

Looks like this is a nebula graph core related, am trying to transfer it there for more exposure.

userName: nebulauser, ip: ::ffff:1.2.3.4 failed: Insert userIpSessionCount to local cache failed.

For some reason userIpSessionCount_.emplace(key, std::make_shared<SessionCount>()); failed?

[doublex]

I think this issue is gone in nebula 3.2

[doublex]

Happens also with nebula 3.2:

hi @doublex , I am suspecting that could this be an issue in the ipv6 env? could you help confirm you are on/configuring with ipv6 environment?

Would surprise me. The server network interface has an IPv6 configured. But the python-client connects via an IPv4.

This PR tests the compatibility of ipv6 https://github.com/vesoft-inc/nebula-python/pull/224 Feel free to reopen the issue if the problem remains.
