UDPSocket crashed while send is been calling (linux)

[skywind3000]

version 0193ca4744 has added UDPSocket, it can work correctly under windows, but in linux it crashed. environment: Linux version 2.6.18-194.3.1.el5.028stab069.6 (root@rhel5-build-x64) (gcc version 4.1.2 20080704 (Red Hat 4.1.2-46)) #1 SMP Wed May 26 18:31:05 MSD 2010

main.lua:

socket = cumulus:createUDPSocket()
function socket:onReception(data,address)
    NOTE("Reception from "..address)
    self:send(data,address) -- echo sample
end
error = socket:bind("0.0.0.0:1234") -- start the server
if error then ERROR(error) end

---

it prompted at beginning: 'ERROR www/main.lua[7] function_00000000406D8368' what's that means ?

and I sent a simple udp packet to CumulusServer, it prompted:

NOTE  www/main.lua[3] Reception from 218.107.55.254:50923
ERROR  www/main.lua[4] (method 'send') Understandable address, System exception: cannot lock mutex

---

then I upgraded poco to the latest version 1.4.5 , CumulusServer crashed when calling self:send

# ./CumulusServer
