dhRichClient3 "Cannot execute SQL-Statement: out of memory"

[tmighty2]

Hello!

I am using dhRichClient3.

I do a lot with sqlite, and at everything works fine for some time, but then at some point of time I get the error "Cannot execute SQL-Statement: out of memory" when calling an update like this:

    Dim Cmd As dhRichClient3.cCommand
    Set Cmd = cnUser.CreateCommand("UPDATE pages SET pagedatetimemodified=?,pagethumbdirty=? WHERE pageguid=? AND pagebookguid=?")

    Cmd.SetDate 1, Now
    Cmd.SetBoolean 2, True
    Cmd.SetText 3, tPage.Guid
    Cmd.SetText 4, tBook.Guid

    Cmd.Execute

This code is fine. I can call it like 20 times, but then at some point of time, it throws this error: "Cannot execute SQL-Statement: out of memory"

I can't really say under which circumstance it happens.

My app shows ~400 mb in the taskmanager.
In the taskmanager, I see that for a split second (right after cmd.Execute) the taskmanager shows 1350 mb for my app.
Then, immediately it flips back to ~400 mb.

So obviously dhRichClient3 does something internally which consumes really much memory for some a small amount of time. What might that be?

How could I debug what causes this out of memory error?

I am using an undo-redo logic with triggers, so the problem is a bit too complex to post it.

That is why I would like to know what I can check first.

Thank you for any hint!
