Weird FTP Connect Error Bug

Hi guys, this error might be familiar to you guys, but I tried searching the
web about this. First off, here are the logs.
(I censored a few details)

2007-09-17 01:04:08.380 Bandwagon FTP[13584] Error: couldn't connect to host
2007-09-17 01:04:08.380 Bandwagon FTP[13584] Headers {
    "220-local time is now 10:05. server port" = "21.";
    "230-user has group access to" = "
12945 ";
} and Error couldn't connect to host

And it cycles that way. What's weirder is it always happens on the 230th, or
231st, or
232nd file download (meaning it already downloaded 230+ items already when
error happens), and for 5 days of monitoring, it always happens this way.

Another weird thing is that it seems to have a "premonition" before this
meaning it shows up that it has somehow disconnected because of timeout
(my FTP timeout is 10 seconds), then resumes cleanly, then after that, I get
error messages:

Error couldn't connect to host

And then it tries to "resume" starting on the first byte (which I might've
miscoded, but
it was just setting the URL and setting options like so:)

curl_easy_setopt(chandle, CURLOPT_RESUME_FROM, currsize);

where currsize is the current downloaded size of the file. I already tried
doing curl_easy_cleanup
and also tried restting the handle, but the error still happens.

Please help me out with this. I'm currently using libcurl v7.16.4. My hair
is thinning and
I'm afraid I might get bald because I'm pulling my hair off because of this

I could give you more info about my code, but I want you guys to know that I
just do the basics
(just setting options and run the download bit).
