Error when defining the time in Parcels Run using SOSE data

Question: Problem defining the time in parcels using SOSE

Question

Currently, the script runs successfully for 10 years using SOSE data from 2006 to 2010. However, when it reaches the 10-year mark, it breaks, and I would like to extend it to run for 50 years.
Below, I have attached the script I am using, along with the error message that appears when it reaches 20% completion (equivalent to 10 years).

Additionally, I tried to run more than 10 years using only one file (corresponding to one year: cubetime=np.reshape(cubetime,(1,73))) of SOSE and it worked. So the problem should be on how the data is defined in the "cubetime". How I can modify the script to solve the problem when using the 5 years of data?
SOSE files are one for each year (2006, 2007, 2008, 2009, 2010) and the data is every 5 days.

Supporting code/error messages

Ufiles  =  sorted(glob(data_dir+"*Uvel.nc"))
Vfiles  =  sorted(glob(data_dir+"*Vvel.nc"))
Wfiles  =  sorted(glob(data_dir+"*Wvel.nc"))
#Sfiles  =  sorted(glob(data_dir+"*Salt.nc"))
Tfiles  =  sorted(glob(data_dir+"*Theta.nc"))
 
times_sose=xr.open_mfdataset(Ufiles,combine='nested',concat_dim='iTIME').time
times_sose=times_sose-times_sose[0]
times_sose_parcels = [datetime(2006, 1, 1)+ delta(days=int(times_sose[t].values)) for t in range(len(times_sose))]
cubetime = np.asarray([np.datetime64(i) for i in times_sose_parcels])
cubetime=np.reshape(cubetime,(5,73))

Thanks for raising this issue, @cristinarumi. You haven't added the code for creating the FieldSet, so I can't check exactly how you set up that part of your script; but I assume you use time_periodic for the looping? It might be then that you entered the length of the period wrong? Otherwise, I wouldn't immediately know what's going on here...
