There are really two different issues here, which perhaps should be split and dealt with separately.
@ekluzek I'm not sure what you intended in terms of the restart time for this test. i.e., did you deliberately want a restart very shortly into the test? In that case, a solution could be to change the ROF coupling for this test to be the same as ATM_NCPL. But we should still determine the cause of the water balance error.
Fixed in release-clm5.0.12
Reopening: It looks like this was fixed on the release branch (in release-clm5.0.12) but the fix hasn't made it to master.
This fix has come to master: ERS_D_Ln9_P480x3.f19_g16.I2000Clm50SpGs.cheyenne_intel.clm-waccmx_offline
has been replaced with ERS_D_Ld5_P480x3.f19_g16.I2000Clm50SpGs.cheyenne_intel.clm-waccmx_offline
.

,ERS_D_Ln9_P480x3.f19_g16.I2000Clm50SpGs.cheyenne_intel.clm-waccmx_offline
is failing the restart test due to some ROF fields (both rof2lnd and lnd2rof).General bug information
CTSM version you are using: release-clm5.0.09-43-gde4a134 (but it looks like the same error occurred in @ekluzek 's testing of release-clm5.0.09)
Does this bug cause significantly incorrect results in the model's science? No

testmodDetails of bug
I think the problem is that this test restarts in the middle of a ROF coupling interval, since ROF is set to couple every 3 hours.
I tried increasing the length of this test to 5 hours, to get a restart at 3 hours. However, this failed with a water balance error at time step 16.
Important output or errors that show the problem
Failure in
ERS_D_Ln9_P480x3.f19_g16.I2000Clm50SpGs.cheyenne_intel.clm-waccmx_offline
These are the fields that differ between the base and restart runs, from cpl.hi:
Failure in
ERS_D_Lh5_P480x3.f19_g16.I2000Clm50SpGs.cheyenne_intel.clm-waccmx_offline
Note that, before this, there were water balance warnings up through time step 3, but then nothing between time steps 3 and 16.
