timer is hung out unexpectedly in a period????

[KNC]

Hi all,

We encountered a very strange phenomenon in our customer machine. Our
timer which runs normally at XX:30 is hung out from 4h30 AM to 10h30AM
everyday. We suspect there is other process or kind of security to
prevent our timer to do its job.

FYI: below is snippet of code which kick off timer to tick every hour.
tmrAddressTimer = New System.Threading.Timer(tmrAddressDelegate, _
Nothing, newdualtime, 3600*000)

newdualtime: time to start at XX:30


Any help would be appreciated,
Thanks,
KNC
