Time-Triggered Network crashing

Question

Hello
I've encountered a problem when trying to use Time-Triggered Network.
My RT hardware are two desktop PC used as ETS targets. They specifications are as follows:
Pentium III 800MHz
two 82550 chipset based network adapter (Intel PRO, but i cant remember
exact name), one for normal Ethernet, and one for deterministic network (both computers connected by crossed cable)
128-256MB RAM
additonally i use another Pentium III as host computer.
My aplication is really simple, one of RT machines generate random
values, and send them to other RT machine. Everything happens in timed
loop.
When i use network-shared variables everything runs smoothly. When i
try to use time-triggered variables, VIs deploy normally, but then one
of RT machines (slave) reboots. Host computer shows synchronisation
window (connecting, 0% progress) and after a few minutes announces
time-out. Rebooting RT target show unhandled exception error in a
moment before reboot, but its really hard to read exception code (it
happens too fast, it is something like 0xC00(few zeroes here)05)
I have also tried to use old AMD K6 computer as RT machine (i am aware
that it is far below requirements) and in this case there is no reboot
but still synchronization isn't happening.
Another strange thing is that my VIs worked correctly for one time (no
reboot, synchronisation done normally), but it happened only once and
naver happened before and after. If i remember correctly i've been
deploying VIs normally, just as usual.
Where lies the problem?
Thanks in advance

Thanks for reply
I've made few VIs from scratch and rebooting occurs every time. They
are basically the same (generating random value and sending it to
another machine) but they differ in details (ie. i've used timed loop
once and normal loop other time). When i use network-shared variables
instead of time-triggered variables everything runs normally.
In a few days (maybe tomorrow) i'll post my VIs and get exact code of
exception that is causing reboot (i have it in lab, and i am posting
from home). Maybe it will help to clarify the situation.
