Many thanks for the info.  I was using a fairly crummy 32 bit box with no PSTN card installed.  There was no degredation of the audio immediately apparent.

FS now tries to determine how accurate the timing is by doing some tests with 1ms sleeps.
Most 64 bit CentOS box I have seen can easily calibrate.
If you are having that error alot but the calls still sound ok, it's safe to ignore it.
you can also start FS with -nocal to skip this test.

Also make sure you do not have any other cpu-intensive application on your box possibly competing for resources.

Hi Anthony,

Many, many apologies to take so long to reply - I failed to notice your response.  Sorry !

It seems to be variable.  Most times (on CentOS 5.3) when I start FS it tells me it is around 1995ms.  Occasionally it is lower (sub 1000ms) and then does not give a warning.

Best wishes
Bruce

we are still wary about 5.3 due to bugs reported in libc.
What number does it say it detected for the gap?

OK - I've realised I do get the same warning with CentOS 5.3, it just goes past more quickly so I didn't see it.  Maybe it is just the hardware ....

Hi,

I wonder if anyone would be able to advise please:

When I build FreeSWITCH on yum updated CentOS 5.4, I get a warning when I start FreeSWITCH that

"Abnormally large timer gap detected"
"Do you have your kernel timer set to greater than 1kHz?  You may experience audio problems".

I get no such warning if I build on CentOS 5.3, and the test timings it measures on starting FreeSWITCH do look lower.  All I was doing to upgrade to Centos5.4 was a yum update on the 5.3 build.

I guess the warning comes from here: http://fisheye.freeswitch.org/browse/~raw,r=16409/FreeSWITCH/src/switch_time.c

This is all on pretty low spec hardware - a couple of different Dell optiplex p4's I use for testing.

Does anyone happen to know if I should just stick to Cent)S 5.3, or use 5.4 and not worry about the warnings, or if there is something I can do to fix the problem it is warning about.  Perhaps it is just that I shouldn't use such crummy hardware?!

Many thanks in advance
Bruce
