fastcgi incomplete headers issues

[robmorin]

I know this has been on here before, but its seems to be a difficult issue to pin down....

I am moving users/websites from vhcs2 over to Omega on a different server, and so far 50% of the sites break due to fastcgi errors problems permissions, whatever....

Is there a way to debug fastcgi to give more info when something does not work.... i always get the same errors, but never know what it might be, sometimes perms , sometimes its something else but the error stays the same.....

[Thu Nov 08 08:35:21 2007] [error] [client xxx.xxx.xxx.146] FastCGI: incomplete headers (0 bytes) received from server "/var/www/fcgi/domain.com/php4-fcgi-starter", referer: http://www.domain.com/index_m.htm

Its driving me nuts....
I have to migrate over 150 websites, so far i have done 8 and 5 of them had issues....

Can someone please let me know if i can do something to increase debugging for errors like these, or explain to me what that error indicates exactly...

here are perms for this site....
