One more thing I have ubuntu 1000hz preemtive kerenel. And we have exclusive usage of pri and meetme conf

Do you think 1000hz could be the issue ?

Also my idle system load is quite high

I'm not sure what we can ask for, and there isn't really any information to go on here. Perhaps a backtrace of the running process, or using strace would help to narrow down what is going on here.

If the reporter can provide debugging information per gdb and strace, then please reopen the issue and attach the debugging information to the issue. I believe switching to res_timing_dahdi will resolve this issue.
