Problem solved.
For experimental reasons I had defined FTP Timeout to zero.
What I didn't know was that the same timeout was used in I.pm
read functions select-function call as a timeout also.
When the data sent from the remote had enough delay, select
would timeout and I.pm would call 'carp'.
As it was, I was executing 'get' inside an eval-block and
was able to caught this one. The only problem was that I
had relied on Net::FTP documentation and only checked that
the return value was defined. After calling 'carp' get
returned zero and halted file transfer. As my script proceeded
I sent the 'pwd' command falling into the deadloc I described
earlier.
Now I would like to ask whether the connection timeout should
be used in rea-timeouts also if zero is a valid value?
