cannot scan large files: No such file or directory: '7za'

[Tietew]

I uploaded a 4GiB file (DVD ISO file) with no extension. (the S3 key is zzzzzzzz/xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx) ServerlessClamscan lambda failed with following error log.

Note: a 600MiB file is scanned and tagged CLEAN successfully.

Do you receive the same error if the extension is included on the ISO?

@dontirun I tried (object key xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx.iso), but received same error.
