Describe the bug
A clear and concise description of what the bug is.

To Reproduce
Two failures in SR0 Rn220 runs.

st_salt = saltax.contexts.sxenonnt(runid=21952,
             saltax_mode='salt',
             output_folder='/scratch/midway2/yuanlq/salt/sr0_rn220',
             faxconf_version="sr0_v4",
             generator_name='flat',
             recoil=7,
             mode='all')
st_salt.make('021952', 'raw_records_simu')
...
ValueError: Attempt to create chunk [021952.raw_records_simu: 1623158479sec 407739940 ns - 1623158485sec 245093400 ns, 148275 items, 6.2 MB/s] whose data ends late at 1623158485245312770

However, there is successful example in SR1 BKG run:

st = saltax.contexts.sxenonnt(output_folder='/scratch/midway2/yuanlq/salt/tests',
                              runid=40671, saltax_mode='salt')
st.make('040671', 'raw_records_simu')
