[gmx-users] Warning: correlations not long enough

In my simulations ,I have a Peptide in aqueous solution with a cosolvent.
For more number of hydrogen bonds like peptide water, water-water, there
are no warnings
But for Peptide cosolvent, there are 315 hydrogen bonds and it does the acf
It shows warning: correlations not long enough
My original time step was 0.002 and I changed it to 0.0005 and even lowered
the output frequency of coordinates
Doing so gave me a 80GB output file!
Still the problem persists..
The lifetime that is output on the screen is 45 ps.
Since it writes that the lower half of the correlation function was fitted
and then this is calculated, can I quote this lifetime? Is it accurate?
