Global proxy suffers from 'illegal argument String.blit' while uploading

[toolslive]

It causes either to the AlbaOsd to be disqualified (see #797 ) or (when the Fail fast workaround is in place, the proxy to shut die)

@domsj can you pick this one up in the context of trying to fix the fail fast issues.

[domsj]

Great, just the ticket I needed, I'm hoping it would be fixed (for real this time) in https://github.com/openvstorage/alba_ee/pull/167. Will be available as of alba 1.5.20 / 1.6.2.

@domsj what is the status of this ticket? Can this be closed

[domsj]

This is not yet fully fixed. @andersfugmann made it reproducible in https://github.com/openvstorage/alba_ee/pull/256 after which I analysed the (debug) logs and made the following change, which should make it occur less, but it's not a proper fix: https://github.com/openvstorage/alba_ee/pull/250. So some work remains to be done, and this issue should not yet be closed.

actually this could be closed as a duplicate of https://github.com/openvstorage/alba_ee/issues/187 (or the other way around)
