FTP file name character limit???

[a5s]

Hello,

I am developing an application that needs to FTP files to a remote destination. Currently everything works as expected; however when I try to send a file with a name that exceeds 150 characters I am experiencing issues. It appears long file names will cause a Socket exception when trying to rename the file. I believe the problem occurs when the file is being renamed from the ".writing" form to the target file name, because the file is transferred successfully as ".writing" before the exception is thrown. The file names I am working with are very long and my application needs to be able to handle file name lengths of at least 256 characters. Is there a way to fix this issue?

Thanks in advance

can you post an exception stack trace?

Here is the full stack trace (I changed project/file names and directories):

[oleg.zhurakousky]

Are you abel to transfer the files via command line?
This might be a limitation of your file system

[a5s]

Yes, I am able to transfer file names greater than 150 characters from the command line. However it does appear rename times out...

421 Service not available, remote server has closed connection

[oleg.zhurakousky]

what version of SI you are using? Looking at your stack trace seems like a bit old

[a5s]

We are using version 2.0.3

[oleg.zhurakousky]

That's pretty old. So although I am pretty sure it wil not resolve your issue I'd stil suggest ti upgrade to 2.1.3 andpost the freshest stacktrace so we can figure out what's going on.
