Hi! <br> <br> I am running a parallel program and getting the attached err_log. The problem seems to be strange as some times the code runs normally with the same input and some times not. If the cpu usage is low, mostly i am not getting this err_log..
<br> Actually, what the program does is:<br>when master gives a command to the slaves, they take data from the nfs directory. They create a temp directory in /tmp and after finishing the work, the results will be copied back to nfs directory.
<br>In this process some problem is coming. Actually this program worked fine for a month or so,, But now suddenly, without changing the code and for the same input we are getting this problem..<br>What could be the problem..??
<br>Please help me in solving the problem..<br>Thanks in advance,<br>Kalyani<br><br><br>
