Hi,

Based on he output, it looks to me that you are reaching a limit of nested archives, which means that you have file which is archived multiple times.

According to documentation, max scanable nested archive can be up to 5 levels, but, based on couple of production WSAs that I have, it looks that it is configured at 2 by default (which is contributing to my theory).

You can check this under Security Services / Acceptable Use Controls. Also, you can try to increase it to max of 5 (which can have negative impact on WSA) and check if that helpes (ideally, if you can reproduce it with same file).

BR,

Milos
