Hi wanghe,
Hard to say exactly what’s happening there but, at a high level, vls tries to
clone a vcl session from one worker to another and the rpc does not return
after 3s.
Are you running this at scale or does this happen with few sessions?
Also, make sure that a session does not constantly bounce between app threads.
If that’s the case, most probably multi-thread-workers is not the right
approach as it was mainly meant for scenarios where a session is allocated on
one thread and then it’s used on another.
Regards,
Florin
