Software would crash at 1pm every day

Ok we have a Server 2012 R2 Ess running 2 x 3tb ssd drives in a raid 1 mirror and the only error or warning at 1pm is

svchost (7440) A request to write to the file "C:\Windows\system32\LogFiles\Sum\Svc.log" at offset 5214208 (0x00000000004f9000) for 4096 (0x00001000) bytes succeeded, but took an abnormally long time (20 seconds) to be serviced by the OS. This problem is likely due to faulty hardware. Please contact your hardware vendor for further assistance diagnosing the problem.

it can be due to disk problems
is the firmware fo your SSD's updated?
test the SSD with the manufacturer's tool - what model is this?
Odd. is that same error logged every day at the same time? Does it appear at other times too?

It happened again today at 1pm and cut us from our software program but it does have that same error every now and then but the software does not crash.

Nobus sorry the drives are not ssd they are HPE Midline
Hard Drive - 3 TB - SATA 6Gb/S

well - test them also with the manufacturers utility; i use the ubcd for this
Hardware diagnostic CD    UBCD
go to the download page, scroll down to the mirror section, and  click on a mirror to start the download
Download the UBCD and make the cd   <<==on a WORKING PC, and boot the problem PC from it
Here 2 links, one to the general site, and a direct link to the download

since the downloaded file is an ISO file, eg ubcd527.iso - so you need to use an ISO burning tool
if you don't have that software, install cdburnerXP :

If you want also the Ram tested - run memtest86+ at least 1 full pass,  - you should have NO errors!
For disk Diagnostics run the disk diag for your disk brand (eg seagate diag for seagate drive)  from the HDD section -  long or advanced diag !  (runs at least for30 minutes)      

**  you can make a bootable cd - or bootable usb stick
*** note *** for SSD drives  use the tool from the manufacturer, like intel 's toolbox :

for completeness -here's how i handle disk problems :

==>>****in order to be able to  boot from CD or usb - you may have to disable secure boot in the bios
Agreed. if it isn't at 1pm every day specifically I would suspect the HDDs initially and recommend running tests on them as above.
If they pass I'd recommend some basics on the HDD/RAID controller. check its firmware is upto date. check the battery is OK (if there is one) as they can both cause odd behaviour.

If there is any regularity to it (as you initially suggested1pm every day) then we may need to take a different approach.
don't you have something like an av scan or backup scheduled at 1 pm ? stressing a stressed drive can make stuff hang... btw 3xraid1 is not a very cost-efficient setup.

Okay will check the drives and also check scheduled tasks.

Hi all,

Sorry for wasting your time, turns out there was a scheduled task running at 13:00 to do an additional copy of data that a 3rd party supplier had setup without our knowledge. We disabled this as a test and we had no further issues at the specified time. We've since moved that scheduled task to a time outside of normal operating hours and all is well once more.

Thanks for the replies.
