to wogole jest dziwna sprawa, jak szanowny lists admin przepusci maila z
bt i strace to bedzie wiadomo wiecej ale.....
...nie wiem do konca jak dziala ten caly lftp ale jest niezle zakrecony
spedzilem z godzine klikajac n i s w gdb i dalej nie wiem na czym to
polega :) wiem ze definiuje sobie joby i potem w petlach sprawdza czy
sie wykonaly, pobiera tez czas z systemu, nie wiem czy to wazne ale
kiedy debugowalem ten przypadek - problem nie wystapil klikajac tylko s
kiedy jednak ponownie wpisalem ls i tym razem continue - wysypalo sie znow
tak (inaczej niz w mailu ktory czeka na zatwierdzenie :) ):
