[Pw_forum] Failure during collective

[paresh rout]

Dear all,

I am getting a strange error while performing scf calculation using two
different Hubbard U values for my system. When I use U=3.5 eV  job runs
fine but for U=7.4 the job  stops after some iterations(very close to
convergence). I tried a lot to overcome this problem but unable to sort out
by myself. Any help would be highly appreciated. I attach the Input ,
output and the error file below .


Thanks
Paresh
