System-console with FPGA Stratix IV GT 230

Thank you Dave! On the basis of board HTG-S4GT-PCIE -230 I developed a fairly complex project, which consists of a controller PCI Express 2.0 x8, MAC 10G, NiosII etc. All of this works stable. Then there is a need to observe some of the registers and memory locations and I decided to use the system-console. In the single appeals operations such as master _read _32/master _write _32 are working normally. The problem manifested itself when I wrote the script in tcl using after time proc _name. After a few minutes (from 1 to 10) FPGA configuration has to lose. I tried to make a very simple project and the problem persists. The board ieetsya configurator MAXII. It manages the configuration pins nconfig etc. I tried hard to connect the findings programming inactive levels - does not help problem repeat.
