[GHui]

I code a simple server and client. But the server is locked at apr_socket_send.
 The server apr_socket_send is block.
 Any help will be appreciated.

Hi GHui,

as you can see, apr_getnameinfo() does not give a different answer
than the system's one.

Address 172.18.4.2 really resolves to localhost in your environment,
whereas 172.18.4.3 is unknow.
You will have to take a look at your DNS (172.18.0.1) configuration.

Regards,
Yann.

 Non-authoritative answer:

 I am not an expert in this apr routine, but I think it might help if you
 gave the command-line argument you used when testing your program.

How to release apr_socket_accept memory pool

I code a server with apr_socket_accept and apr_pollset_poll. But 
apr_socket_accept and apr_pollset_add take up the memory pool. I cann't release 
or clear memory pool. So it take up more and more memory.

Can you not solve that problem by using a subpool for those
functions?  That way you can give the subpool the lifetime
you need it to have, regardless of other resources that
prevent you clearing the parent pool.

 


If do this, every connect need create a subpool, and clear mpool when close the 
connect.

apr_socket* server takes up more and more RES as it runs.

[GHui]

I use apr_pollset_poll and apr_socket_accept to accept short client connect. 
Only one client connects it every second. The RES increase from 3068 to 33m 
when it runs for about 12 hours, and VIRT is 2106m when the program starts. If 
there is no client connect, the RES doesn't rise.

Any help will be appreciated. GHui
