syscall interrupted during sftp transfer

[god12]

While copying plenty of files to sftp server (note: sftp-only, no shell support) I experience multitude of errors regarding interrupted system call (прерван системный вызов (4)). If I choose "repeat" in this dialogue the transfer resumes normally - until it's interrupted again later on on some other file.

I do believe this is an mc issue because:

• transfers to the same host with duplicity gave me no errors at all
• choosing repeat result in always successful transfer

Too tight timeout somewhere or no attempt to repeat the read/write before presenting user with scary red error dialogue?

Also having more explicit error would help in troubleshooting - I mean, yepp, some system call failed - which one?!
