[Serusers] Grandstream firmware 1.0.4.39 subscribe.

Hello all, I've been experimenting with Grandstream beta firmware for my budgetone 102. Result: every version > 1.04.18 kills all ser processes except one that just hangs and needs to be terminated with SIGKILL. Ser itself is 0.8.12 on linux 2.4.24, gcc 3.2.2, libc 2.3.2. Only this shows up in syslog (debug level 3): [/usr/local/sbin/ser] BUG: tcp_main_loop: dead child 2 This is the request that chokes ser: U 192.168.0.3:5060 -> 212.238.149.10:5060 SUBSCRIBE sip:bandsla.org:5060 SIP/2.0 Via: SIP/2.0/UDP 192.168.0.3;branch=z9hG4bK446fd67e04e4a465 From: <sip:f.kuipers@bandsla.org:5060>;tag=d64e39684c2d5733 To: <sip:f.kuipers@bandsla.org:5060> Contact: <sip:f.kuipers@192.168.0.3> Call-ID: 48adbbd50b3eaa53(a)192.168.0.3 CSeq: 54360 SUBSCRIBE User-Agent: Grandstream 1.0.4.39 Max-Forwards: 70 Allow: INVITE,ACK,CANCEL,BYE,NOTIFY,REFER,OPTIONS,INFO,SUBSCRIBE Event: message-summary Expires: 600 Accept: application/simple-message-summary Content-Length: 0 Hope this is usefull, Friso Kuipers.
