clock stopped/lags [Solved..for the time being!]
« on: March 26, 2014, 12:38:12 pm »
Hello again to all PepperMinters!

Been using P4, 32bit version a few days now .. just noticed clock stopping for 2-3 minutes, then starting again, only to stop, or lagging for a couple seconds.  Again, not a real big deal.

At the time it stopped for a couple minutes, only had Chromium running with a 2 fully loaded tabs, CPU usage around 5%, RAM usage around 20%.  This is an Acer Aspire 1/D257 with dual Intel Atom N570/1.66 GHz processor and 2 GB ram.  [1 GB added by me]  Every thing I put it thru seems to execute in a timely manner.

I did note that moving panel position from bottom to top and back again got clock running when it stopped.

If more technical information is needed please ask.  Not a real big deal, more of a glitch.

Regards,

Ron

When this happens are you running on AC or battery?  If battery, try disabling Power Manager for a while and see if the problem persists. 
We are talking about the digital clock in the systray, correct?

On AC, I actually take batteries out of all my netbooks [2] and Acer Chromebook.  So 100% AC.

And yes, digital clock in systray .. do have set up to display am/pm time format, and day and date.

Does running:
Code: [Select]
lxpanelctl restart
improve anything.

Might also be worth checking:
Code: [Select]
top
and seeing if anything jumps out at you.

Could be hardware related, i.e.  loose, dying or faulty CMOS battery.   
You might try clearing the CMOS by removing the battery for a while......a couple of hours, maybe, but only if you feel comfortable pretty much dismantling the computer. 
I'll do some checking around but I'm out of suggestions for now. 
Did restarting the panel, as PCNetSpec suggested, help out?

I will reset panel in a bit when I get that netbook up and running again.  Most likely will not take clock battery out.

Seems to be an intermittent situation .. and not worth investing too much time in .. however, I will reset panel.  Did do a reboot, and a shutdown/restart.  Clock still seemed to lag that couple seconds, not completely stop as I noted before.

Thank you .. will try set, and let all know, and mark subject accordingly.

Anything using a lot of CPU or memory...

When you start top it will be displaying the processes using the most %CPU

To select %MEM as the sort field, hit "Shift+F", then use the up/down arrow keys to select "%Mem", then hit "s", then "Esc"

top will now be displaying the top memory using processes.

is Xorg permanently using 80% ?

Are you running anything graphics intensive ?

Hey PCNetSpec>  will look again Friday .. from my memory though just the two items that I copied where the highest around the clock situation.  At the time I 1st noticed it only had 2 tabs open in Chromium ... nothing else running.  And those 2 tabs where pretty generic & loaded fully.

OK...please excuse the extensive data below .. all in the spirit of helping.  So I did the top command, sorted by memory.  3 sets of data, 1st 2 seem to be static, last 1 is dynamic and live.  Again nothing pops out to me as being excessive cpu and/or memory usage.  Again, the clock lagged 2 seconds every now and then, all I had open was Chromium with 2 tabs used, one in gmail, one in all place the Peppermint Home Page.  I really have not noticed any other type of lag in doing what I want to do.

Re: clock stopped/lags [Solved..for the time being!]

Did restarting the panel make a difference or not ?

just as a matter of interest, if you run this in a terminal:
Code: [Select]
xclock -update 1
does xclock freeze at all?

[EDIT]

I just enabled the display of seconds in the lxpanel digital clock .. and sure enough it pauses for a couuple of seconds every now and again .. weird  :o
xclock doesn't .. so it's gotta be a bug with the way the digital clock panel applet refreshes its display
