THPS2X Syslink crash

Happens if too many servers are present (this is where data is written to driver?):

Hardware watchpoint 1: *(int*)0xD004D048

Old value = 1065353216
New value = 1500647462
0x00215adf in ?? ()
(gdb) pint $eip
Undefined command: "pint".  Try "help".
(gdb) print $eip
$1 = (void (*)()) 0x215adf

And this seems to copy server to database (this in particular copied string?):
