Xshell4 hang up when transfer a large file using zmodem

 
First, Xshell is a handy tool, except a small bug always break my workflow.

This bug is same as someone mentioned before: Xshell is hung up when i use command "rz"or "sz" download a large file.

There are two exception:
1. zssh in my linux box can successful transfer these large files to/from server.
2. Xshell can transfer large files to/from my linux box which running rz/sz 0.12.21.

my environment:
Server: sz/rz version 0.12.20 bundled with Red Hat Enterprise Linux AS release 4 (Nahant Update 3)
Xshell: Xshell4(Build 0113) (several earlier versions cannot work, but i cannot remember the exactly version number, sorry)
linux box: debian stable

Program Ver. : Xshell 4

Thank you for sharing this information. I have forwarded to our developers and will try to duplicate the problem. I think there is certain combination that makes this problem because we weren't break the transfer unless we manually discontinues the transfer. This information can help us find the cause.

I have the same bug with rz.
when i choose a file in a deep directory (it need much more time),
it will breakdown....crash.

if i choose a file quickly, it is ok.

ps : i think it maybe the rz deamon'timeout is too short.

xshell (build 0213)

Xshell rz Upload files function is very fragile, and a few updates did not solve, especially slightly larger file uploads, and often fail.

This problem seems to occur to some Xshell users and our developers are trying hard to improve stability and performance of z modem.

If you know steps to replicate the problem, please let us know. It will help us greatly in solving this issue.
