Each script was using their own connection to MySQL server (mysql module). They are working properly on FC1 - FC4 linuxes (PHP 4.3.11 - 5.0.4). I tried for the first time to tun them on FC5 which includes standard rpm packages - PHP 5.1.4 in this case (iptables and selinux turned off). I noticed that my threads fail with message "server has gone away" when using "mysql_select_db. The behaviour is the same regardless if it is connection via unix socket file, tcp/ip connection to localhost or some remote IP address. It does not matter what MySQL server version I am connecting to (tried with 3.23.58 - 5.0.22) I tried also switch to "mysqli" module on FC5 and the script started working properly again so I assume only "mysql" module is affected. I do not have major changes to standard php.ini... just max_execution_time=300 and memory_limit=32M. Test script is just a minimal version (without any threads synchronization, etc. stuff). Please help :-) Reproduce code: --------------- http://www.buleksoft.pl/mysql_pcntl_test.html Expected result: ---------------- [EMAIL PROTECTED] ~]# php -q test.php Forking thread number 0 Thread 0 doing some mysql tasks Forking thread number 1 Thread 1 doing some mysql tasks Forking thread number 2 Thread 2 doing some mysql tasks Forking thread number 3 Thread 3 doing some mysql tasks Actual result: -------------- [EMAIL PROTECTED] ~]# php -q test.php Forking thread number 0 Thread 0 doing some mysql tasks Forking thread number 1 Thread 1: Could not select DB because MySQL server has gone away Forking thread number 2 Thread 2: Could not select DB because MySQL server has gone away Forking thread number 3 Thread 3: Could not select DB because MySQL server has gone away ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=38228&edit=1
