File Write Fail

[kenadol]

I get this error when uploading an image to Filezilla.

Stor/A360/c2/Accepts/392ELD23900489_Coast
150 Opening data channel for file upload to server of * /A360/c2/Accepts/392ELD23900489_Coast
550 Writing to file failed.

What is a likely cause.

Thanks

Ken

For some reason the server cannot write to the target file. Disk full? Wrong filesystem permissions?
