Token length exception when using a mask

[voidseer]

Figured out that I needed to move the mask to the end of the line like this:

Code:

hashcat.exe -m 1000 -a 3 -1 ?l012345!_@ -2 ?l?u012345!_@ -3 ?l?u!_@ -4 ?l!_@ -o cracked.txt hash.txt ?u?1?1?2?2?1?2?2?3?2?3?2?4

But now I'm getting this error:

Integer overflow detected in keyspace of mask: ?u?1?1?2?2?1?2?2?3?2?3?2?4

I'm guessing that means it's not feasible.
