[Serusers] non-responsive SER 0.9.6

Hi, I think this issue was already risen a while back, but seen that there is no answer, i will insist :D My SER becomes completely unresponsive (UDP and TCP) after a while. I started it 3 days ago and have a monitoring script that sends 1 REGISTER every 10 secs (plus a few other phones). This morning that SER was totally stoned! :( I have tried sending via UDP and TCP ... same answer (that is, no answer). But, the fifo (thus, part of SER) still works (i can do a serctl moni). I am trying to investigate myself ... what can i do? can i force a core dump from the shell (sending some kill signal) to the already stoned SER? Regards, Cesc
