That depends on the force field convention. It is not universally
appropriate to constrain all bonds (and certainly should not be the
"solution" to just "make the warning go away"), and the warning from
grompp may not actually be the source of any problem.

Dear Gromacs users,
I am trying to perform a nvt equilibration, but when I generate the .tpr file I
get a warning indicating that a bond is oscillating too fast:
The bond in molecule-type MOL_1 between atoms 38 C21 and 39 O22 has an
estimated oscillational period of 2.4e-02 ps, which is less than 5 times the
time step of 1.5e-02. Maybe you forgot to change the constraints mdp option.
I have ignored it with the -maxwarn option and I obtain the .tpr file. However,
when I run the simulation I obtain this error?
Too many LINCS warnings (1630)
Are the error and the warning related? How could I solve the Lincs error and
the warning?
I attach the .mdp file.
Thank you in advance,
C.
