Bug #13400: ftp functions are sometimes REALLY slow

From: woprog@hotmail.com Operating system: Red Hat Linux 7.1 PHP version: 4.0.6 PHP Bug Type: Performance problem Bug description: ftp functions are sometimes REALLY slow I lately installed ProFTPD. This is on of the fastest FTP daemons I know. I've made a site which heavily uses FTP connections to a computer in the same subnet (100Mbit connection between the two). It's really strange. Sometimes the ftp functions (especially ftp_nlist and ftp_rawlist) work fine, sometimes it takes like 5 minutes before the call to the function ends with an empty array as a result... this is really annoying. I've searched user submitted notes about this problem, but couldn't find anything. I don't know if this is a known issue, or maybe it's just a configuration problem on one of the two involved Linux PC's. What I do know is when I restart httpd, the slowdown is always over immediately. I DO close every ftp connection I make! Please help... -- Edit bug report at: http://bugs.php.net/?id=13400&edit=1
