Thanks Alex - I certainly could try any number, that's why I changed it from 60 to 90 and then 120.
Would you care to elaborate why a timeout of 300 seconds would do what a timeout value of 120 seconds doesn't accomplish? Considering that the upload fails way EARLIER than the 120 seconds that are already configured? In most cases it fails in under 50 seconds?
Here are a round of most recent tests (with the timeout of 120 seconds for FastCGI):
1.320 KB - uploaded OK
2.259 KB - uploaded OK
4.440 KB - FastCGI failure message after 75 (!) seconds
2.524 KB - FastCGI failure message after 40 seconds
another try same file
2.524 KB - FastCGI failure message after 45 seconds
2.288 KB - uploaded OK
another try same 2.524 KB file as before
2.524 KB - FastCGI failure message after 46 seconds
another try same 4.440 KB file as before
4.440 KB - FastCGI failure message after 66 seconds
another try, same 2.288 KB that uploaded OK before
2.288 KB - FastCGI failure message after 36 seconds
