Thank you for taking the time to write to us, but this is not a bug. Please double-check the documentation available at http://www.php.net/manual/ and the instructions on how to report a bug at http://bugs.php.net/how-to-report.php When using threads you should not be using persistent connections, because PHP cannot identify existing connections as already avaliable and therefor opens a new persistent connection each time. Previous Comments: ------------------------------------------------------------------------ [2004-04-22 08:36:07] moreau at myrealbox dot com Thanks for your answer too, I didn't know that persistent connection is not closed after ending script. But I don't agree that such behaviour as I describe is normal. As I mentioned pconnect generate new thread in each new running script. BUT THIS IS THE SAME SCRIPT! So as said in documentation pconnect should REUSE old connection , BUT DON'T generate new connection. In practice - pconnet don't close any connection at all, but don't reuse previous connection and generate new. Is this also correct behaviour ? ------------------------------------------------------------------------ [2004-04-22 01:54:05] [EMAIL PROTECTED] Thank you for taking the time to write to us, but this is not a bug. Please double-check the documentation available at http://www.php.net/manual/ and the instructions on how to report a bug at http://bugs.php.net/how-to-report.php Persistent connections remain active until the Apache is shutdown. This is expected behavior. ------------------------------------------------------------------------ [2004-04-21 22:02:35] moreau at myrealbox dot com Yes, significantly. Each script is successfully ended , so apache returns in normal state ( minimal threads and process - as pointed in config ) after long timeout ( when pages aren't requested ). But MySQL has many threads and no one of threads never die. ------------------------------------------------------------------------ [2004-04-21 19:19:51] [EMAIL PROTECTED] mysql extension will create one connection per database connect string per PHP interpreter context, i.e. one per Apache thread or child. Is the number of connections you are seeing exceeding your Apache thread count? ------------------------------------------------------------------------ [2004-04-21 19:17:21] moreau at myrealbox dot com Description: ------------ mysql_pconnect every time generate new connection and never kill previous. As result - MySQL generate many threads for handling each query and after too many connection hangs. This never happened if use mysql_connect and mysql_close in each page. I use apache2 . php compiled as module. apache use mpm=worker. I don't know whether it problem in threadead apache or common problem in php with mysql_pconnect. mysql_pconnect in current state cannot be used for accessing to mysql. ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=28098&edit=1
