Hi, Your server most probably can handle the load. It depends of course on how intensive the processing is. The kind of error you are getting (port 80 **** Hit EOF while fetching headers) suggests that the problem is not in Django but in Apache, or maybe you are hitting some operating system limit. However nothing is certain without more information.
If you haven't already done so, you should configure Apache and syslog to use a timestamp that is accurate to the microsecond. You can then check to see other log files such as /var/log/syslog (assuming Linux) to see whether they have more information than the apache log at the exact time the error occurs. Given that this is most probably not a Django issue but an Apache issue or an operating system issue, you may be able to get better help elsewhere, for example in serverfault.com. Regards, A.
