I've been getting a weird error occasionally when I restart a job that states "negative record length error. Fatal restart error." It seems to only happen when I use RKS. Here's an example of what I'm doing. To start, here's the initial input.
water.inp:
angstrom
geometry={
O
H 1 1.0
H 1 1.0 2 104.5
}
basis=6-311g
file,1,test_1
file,2,test_2
{rks,b3lyp}
{optg}
{frequencies}
This is run with the -I and -W flags so that I save the two files. Then, I modify the input file and get the following output file.
Nodes nprocs

Distribution of processes: nprocs(total)= 8 nprocs(compute)= 7 nprocs(helper)= 1

Negative record length. Fatal restart error

It doesn't do this when I run MP2, only when I run DFT.
