 Thanks for retesting.
 I created a test case where 90 % of memory is in use on an 8 GB VPS
 (Cyberduck running in the background before filling up the memory). After
 doing any action Cyberduck immediatly crashed.

 So: This is a major issue I'm currently investigating but it might take
 time as this is not easily resolved. There is not "just" the 4 GB limit
 but also the limitation that if Cyberduck allocates space outside the
 first 4 GB of system memory it will crash.
 Or in other words: It does not run out of memory (not even near maximum
 memory usage) but runs out of addressable memory space which presents
 itself in a OutOfMemory error.

 The IP disconnect should not affect Cyberduck uploading files as it just
 repeats until it can upload successfully.

 Just for my records: Out of 32 GB you had 22 GB left, then 10 GB had been
 in use which could lead to this error.
