[Java SDK V2] too_many_write_operations while uploading

Hello,

we are uploading a quite a lot of files in 4-6 threads and it is very likely, that other users write into our repository at the same time. Today we started to get "too_many_write_operations" error:

Caused by: com.dropbox.core.RateLimitException: {"error_summary": "too_many_write_operations/.", "error": {"reason": {".tag": "too_many_write_operations"}}}
at com.dropbox.core.DbxRequestUtil.unexpectedStatus(DbxRequestUtil.java:293)

at com.moravia.facebookintegration.connectors.dropbox.DropboxNonBlocking.uploadFileWhenEnabled(DropboxNonBlocking.java:104)

I checked the documentation and it says this:

too_many_write_operations Void They are too many write operations happening in the user's Dropbox.

Is there something we can do with this error so it will not happen so often? We have some client applications that upload files via V1 API (will be replaced in future), some new clients that upload files via V2 API (4-6 threads in total), some users, who use Dropbox application or Web interface and they all work in paralel.
