Re: [Ftpapi] FTP job get stuck

[Scott Klement <sk@xxxxxxxxxxxxxxxx>]

Tom,

FTPAPI is sitting and waiting for data on the network.  It seems, for 
some reason, that no data is coming, so it will sit and wait forever.  
Usually, I see this when a firewall is blocking data. Sometimes, I see 
it on an unreliable network, like cellphone data Or when a network is 
"flaky" (i.e. has a bad piece of hardware , cable, etc somewhere in the 
connection.)  It could be almost anything.

To make your program a bit more robust, I would suggest coding a timeout 
on ftp_conn or ftp_open (whichever you are using) so that when this 
happens, your program will timeout and can detect the problem and notify 
someone to try again.  (Or even could be coded to automatically try again.)

If possible, I would troubleshoot the network, too, to find out why 
FTPAPI is not getting the data it expects...  but, that is beyond the 
scope of what I can do for you in an e-mail :-)
