I too had the same issue, though more programs than just tuxmath were running. In any case, the program was using 99% CPU and caused the entire server to freeze leaving all terminals unusable until I killed the process from the server directly... I've been lucky enough to not have any issues regarding freezes until 3 days ago. Somehow, something I installed has now caused freezes on a daily basis, where the entire server locks up and responds 10-15 minutes later. Since I'm not always at the school, I've shown the teachers to look at the process and memory usage and document what's causing it, though I have a feeling it must be Microsoft office running through wine. When looking at memory usage, it uses 10 times more than openoffice. This is significant enough I believe, to cause the server freeze.
I've tested running fat clients over ldap+samba for about 3 weeks now, and it seems to work fine, except with wireless clients, where its a no go. Logging in takes several minutes and profiles get corrupted easily. The only option I see is wiring everything up, which is the way it should have been done from day one.
