[Wien] Wien2k stops completely

[jjlee at nsrrc.org.tw]

Dear ALL,
 
 
 
    Thanks a lots your suggestions.
 
   I also ever suspected the faluts came form memory failure, so I checked by two method:
 
  1. Before Installing Linux, I run the memtest86 for one whole day, there is no error message.
  2. run ten small jobs synchronally that fully occupied the 4GB memory( use "top" to monitor), then it's all OK! no problem.
 
  So, now I suppose that the memory seem no problem. 
 
Sincerely yours
 
 
JJLee

	Only time I saw behaviour like this it turned out that one of the memory
	sticks was bad on the computer. Could be worth doing a memcheck.
