Hello, This is another strange error i catch by screening it. Materials: =========== 1. Switch 1 (30 channels as main simulation server) 2. Switch 2 (10 channels connects with in/out audio) Step 2.a: 6 times originate skypopen/ANY/skypeswitch1 9999 3. Another PC running skype alone itself as a consumer test, to see what happens in reality traffic. Step 3.a: 1 times with real skype call skypeswitch1 and listen music quality 4. Medium Flood to switch 1 using remaining switch 2 channels Note: When 7 channels are busy for 2 hours. And Problem 1 gets started, the sound gets drop, and start latency, CPU gets overflow, and in the voice there is a wind coming from left (like a storm/cyclone started). Hardware status only for 7 active channels becomes as following: =============================================== top - 13:15:44 up 3 days, 16:12, 2 users, load average: 13.74, 10.06, 5.64 Tasks: 178 total, 3 running, 175 sleeping, 0 stopped, 0 zombie *Cpu(s): 70.4%us, 13.6%sy, 0.0%ni, 15.5%id, 0.2%wa, 0.0%hi, 0.3%si, 0.0%st* Mem: 8177580k total, 3371388k used, 4806192k free, 201836k buffers Swap: 2096472k total, 0k used, 2096472k free, 1283920k cached PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND 18719 root 18 0 434m 96m 6628 S 247.4 1.2 10:59.05 freeswitch 23094 root 15 0 93316 30m 3552 S 10.3 0.4 17:35.42 skype 22932 root 15 0 93568 30m 3556 S 9.0 0.4 20:43.74 skype 22706 root 15 0 92240 29m 3552 S 8.6 0.4 14:55.03 skype .....
