Honestly, i don't know, but it surely consumes resources (network
bandwidth and ???).

From your logs :

> Database: D:\DATASQL\DATA\DATA.FDB
> Allocated 5669 page buffers of 8192 requested
> TS2003 Tue Oct 26 08:37:42 2010
> unable to allocate memory from operating system

here, it's clear, not enough resources.

> TS2003 Tue Oct 26 08:39:07 2010
> Operating system call CloseHandle failed. Error code 6

> Database: D:\DATASQL\DATA\DATA.FDB
> internal Firebird consistency check (wrong record length (183), file:

Here, you need a gfix/backup/restore. Might be due to the previous error.

Now I would suggest you to switch back to SuperServer (i read somewhere
this is the recommended setting for Windows) to keep a clean production
service. This will give you time to tweak Windows (if it's possible).
