#20033 [NEW]: Echoing/fputsing ~11k+ of data to STDOUT causes problem

From: ces@vaultbbs.com Operating system: Red Hat 7.3 PHP version: 4CVS-2002-10-22 PHP Bug Type: Sockets related Bug description: Echoing/fputsing ~11k+ of data to STDOUT causes problem I'm writing a POP3 server daemon in PHP. Incoming requests to port 110 are routed to the POP3 server daemon by xinetd. Everything works fine if I *Telnet* to port 110. Everything also works if I just run the script from the command line. However, if I connect to my server by opening a true POP3 connection (such as from Eudora client), messages greater than about 11k cause problems when they are downloaded. I originally suspected a POP3 implementation problem on my part. However, I've confirmed that if I open a clean (non-Telnet) connection to my server and manually RETRieve the large message, the first 11k is dumped correctly but at about 11k everything else sent by PHP is garbage. It appears as though there were some kind of output buffer overflow. This also appears to damage the socket. It does NOT cause the TCP/IP connection to be terminated, but no additional output is sent and the script becomes unresponsive to additional commands sent to it. This *might* be related in some way to bug #19944 that I reported last week and which I closed this morning.
