RE: [PHP] Why would a socket be unavailable?

Don't know if this will help, but can you confirm whether your while loop is failing on the first time through or a subsequent time through (perhaps by echoing something each time through)?

Hi Warren, There is only one process, and I'm sure I have only one IP address. It's just one script that loops. At the top of the loop, it waits to socket_read some data. If no data appears, I want it to timeout so that it can send the server a ping (which I must do). THAT is where the problem starts. If I don't bother making the socket_read timeout, the loop works beautifully-it just waits and waits at socket_read, and then when data appears, it does its thing, then goes back to the top of the loop and waits again. It's when I set the timeout option, and then it DOES actually time out (because there is no data for several seconds), that it no longer is able to socket_read data from the connection. .Rene On Thursday, May 13, 2004, at 05:57 PM, Vail, Warren wrote: > So you have two processes running, one which is waiting on the socket > connection and another, which we have seen, to establish the > connection. > > Doesn't sound to me to be related to performing blocked/non-blocked > connections. > > What are the odds that you have multiple IP addresses on your machine? > Can > you confirm that both of your processes are using the same IP address > (or > the ip address of the other process)? > > Warren Vail > > > -----Original Message----- > From: René Fournier [mailto:m5@renefournier.com] > Sent: Thursday, May 13, 2004 4:49 PM > To: Vail, Warren > Cc: php > Subject: Re: [PHP] Why would a socket be unavailable? > > > There is no firewall-it's all running locally, on my iBook (with > Firewall off).
