[USR-TC] Did anybody find solution ...

Did anybody find solution for "EXCEPTION 0300 CRASH DUMP" and rebooting some DSPs? Curently I have 2 arcs in one chassis and 10 DSPs - I noticed that DSPs connected to one arc ("arc2") are sometimes rebooted, while other dsps aren't. This "arc2"'s uptime was ~40 days when it rebooted. I think that it is more arc problem than dsp's, because I changed places nearly of all dsps but only dsp's mapped to "arc2" was rebooted.
