[gmx-users] error mesage in log file

[Alberto Malvezzi]

Dear all,

I am geting the following error mesage in my log file just before my 
system craches.
Does anyone knows what is happening?

"    Shake did not converge in 1000 steps
         i         mi         j        mj       before         after    
   should be
