The fact that the server has received an HTTP request doesn't mean that the client has necessarily received the resulting response. Look at the HTTP traffic with a TCP sniffer (ethereal, for example), and you'd expect to see that the server isn't responding to the POST. Probably, the solution is to increase the client timeout, fix the server to be more responsive, or kludge around the problem by setting the timeout to a small value and taking a 500 response to be successful (not recommended!). > I've also measured the time it takes to execute the > LWP::UserAgent->request() method and when these 'timeouts' occur, the > elapsed time is around 0.1 seconds. That does sound unreasonably short, doesn't it? The default is 180 seconds, according to the docs. I know this is obvious, but are you certain you're not setting the timeout somewhere (I haven't read your code) -- either in the UserAgent constructor or with the timeout method? OTOH, have you tried explicitly setting it? $ua->timeout(180); John
