Hi, I have some doubts regarding Axis2C I hope someone is able to answer.

We are developing a REST web service which requires to share information among 
several threads. That is, during the service initialization we create a new 
thread that holds some status and spans more threads as necessary by the 
system.

Our issue is that when using our module with the standalone server, everything 
works fine for low loads, but as already mentioned in other threads in this 
mailing list that server does not scale for high loads.

On the other hand when using the module through mod_axis2 (with apache 
configured with the mpm-worker) we have quite strange behavior:
- When not using the keyword Axis2GlobalPoolSize our service gets initialized 
several times, and we are not able to share information among threads, which 
is weird since we should be able to share info among threads. Just in case we 
configured apache to span only one process with threads.
- When using global pools the module is initialized just once but once again 
the information is not shared among the different threads. We tried using the 
axutil_allocator_switch_to_global_pool and its local counterpart to no avail.

Is there any way of making the information in several threads globally 
available?, the most strange behavior is that using the standalone server the 
code works properly...

Thanks in advance,
	René
