[OpenSIPS-Users] What does mean : "We have reached the limit of max async postponed chunks"

Hi Rodrigo,

This is related to async writing to a TCP connection. If the connection 
is blocked for writing (it still is in connecting phase, or it is simply 
blocked as the other end does not read the content from the TCP pipe), 
OpenSIPS buffers the data that needs to be send on that TCP conn (to 
avoid blocking at script level).

The error says the connection reached it maximum allowed capacity on 
buffering. See:
http://www.opensips.org/html/docs/modules/2.2.x/proto_tcp.html#id293474
