[WD22] Windows services consumes a lot of memory when idle over the time (no replies)

HI,

I have created a couple of windows services (windows 2012R2). Most of the time they do nothing, but the memory consumption growths over the time from 3 MB to 100 MB after 3 hours. I have no idea why.

I have a table "input" with a boolan field "done"

The main code is only:

hopenconnection(ccc)
for all input where done=false
.....
.......
end
hcloseconnection(ccc)

Any Ideas ?
