ALL, I just upgrade FS to 16992. 1) timer warning: How's possible the 10000 microseconds? audio sounds ok. [WARNING] switch_time.c:206 Timer resolution of 10000 microseconds detected! Do you have your kernel timer set to higher than 1 kHz? You may experience audio problems. uname -a Linux xxx.idapted.com 2.6.22-14-server #1 SMP Tue Feb 12 08:27:05 UTC 2008 i686 GNU/Linux I used a script to check the interupts :~$ while :; do cat /proc/interrupts |grep LOC; sleep 1; done LOC: 14892854 14892843 14892841 14892830 LOC: 14892955 14892944 14892942 14892931 LOC: 14893056 14893045 14893043 14893032 LOC: 14893157 14893146 14893144 14893133 LOC: 14893258 14893247 14893245 14893234 LOC: 14893359 14893348 14893346 14893335 LOC: 14893460 14893449 14893447 14893436 2) run dingaling with client mode. dingaling doesn't pick up answer. I originate a call from FS, the console blocks, gtalk client ring and it looks ok when I hit answer, but no sound, FS console still blocks. a few seconds later gtalk client shows: Sorry! The voice chat with language_lesson failed because of a network problem at 5:50 PM. Please try again. Click here to report this to Google. here is a log with bgapi: http://pastebin.freeswitch.org/12434 rev 14696 works on the same server same conf. another server running 16958M works at the same time. I have no clue to check, is it related to the timer as in 1)? can some help me to take a look? let me know if you need "dl_debug on" logs. Thanks.
