RTAPI: ERROR: Unexpected realtime delay on task 1

Hey,

Computer: Dell Optiplex 745 no video card.
Linuxcnc: 2.7.3 wheezy from CD
Cards: 5i25 to 7i77 external power from computer to 7i77 leds lit.
Dmesg:


bottom of which says:
[ 166.939516] RTAPI: ERROR: Unexpected realtime delay on task 1
[ 166.939519] This Message will only display once per session.
[ 166.939520] Run the Latency Test and resolve before continuing.
[ 166.939637]
[ 166.939638] In recent history there were
[ 166.939639] 78048, 31920, 62728, 62752, and 63168
[ 166.939640] elapsed clocks between calls to the motion controller.
[ 166.939644] This time, there were 65624 which is so anomalously
[ 166.939645] large that it probably signifies a problem with your
[ 166.939661] realtime configuration. For the rest of this run of
[ 166.939662] LinuxCNC, this message will be suppressed.
[ 166.939663]
[ 166.940687] hm2/hm2_5i25.0: Smart Serial port 0: DoIt not cleared from previous servo thread. Servo thread rate probably too fast. This message will not be repeated, but the hm2_5i25.0.sserial.0.fault-count pin will indicate if this is happening frequently.
[ 166.941461] hm2/hm2_5i25.0: Smart Serial Comms Error: There have been more than 1 errors in 10 thread executions at least 200 times. See other error messages for details.
[ 166.941465] hm2/hm2_5i25.0: ***Smart Serial Port 0 will be stopped***



This happens as soon as I select the config file and press OK

Sorry but I don't know what to make of this error
Base Jitter was set to 30,000 in PNCconf.

Any Help Appreciated.
Thanks

Your servo thread is way too fast
A typical servo thread rate for a velocity mode servo drive is 1 KHz (= 1000000 ns)

Did as you said. Now it works.

Thank you
