Files from specific sizes instantly disappear after encryption

[NicolasKritter]

The retreiving process fail with 404 when requesting encrypted files with certain size (trying to retreive from the same node or other node) but not with other size

It failed with these size

• 16 154 ko
• 16 236 ko,
• 16 254 ko
• 16 354 ko

However, it work with all other size (even 16 054 ko and 16 454 ko)

--> An encrypted zip with size from 16.1M to 16.4M diseappear instantly ?

Notes:

• The whole uploading + encrypting process succeed (I have a hash and no errors)

• I don't have this problem when I don't use encryption.

• I tested it on 2 different private network, same result

• I haven't tested with other file format

System information

Version: 0.5.7-stable
Go Version: go1.13.3
OS: linux Ubuntu 18 server
full node (not tested on lightnode)

Expected behaviour

Retreiving the content when sending a request to the localhost api

Actual behaviour

Geting a 404 error when getting file (even instantly after uploading it on the same node)

Steps to reproduce the behaviour

• truncate -s 16254k test.zip (to create the file)
• swarm up --encrypt test.zip
• (enc the hash with access new act --grant-keys), also fails with the hash+key from the cmd above

curl localhost:8500/bzz:/$hash/ -o result.zip

Backtrace

Code: 404
Message: file not found bzz:/... (hash) .../: no suitable peer
