Re: [Boost-users] Is serialization thread safe?

We use boost serialization for sending notifications from a server to
multiple clients. The problematic scenario is when two client threads within
the same process deserializes the same notification. In your words: the same
archive into different object from different threads.

The same object? - would this be different archives into different objects
or the same archive into different objects from different threads.

It's not clear what is being done here.

The "serial" nature of the process excludes a number of mult-thread
scenarios by definition.I believe that serialization is thread safe in all
contexts where it makes sense to access serialization from different
threads.
