She said sometime use rendering function for big video clip will hang and close program, i can't find any log record for after effects,
the problem cause by Ram not enough or another? Please give me some suggestion, thanks a lot for your help!
Without knowing anything about your comp like what effects you use and things like exact render settings nobody can tell you much. You could be running out of RAM indeed, but then just the same you could run out of disk space, a specific effect kicks in, your footage is damaged at that point and so on...
