Hi all, I've some problem with my Mysql servers since the beginning of this week.
I've got plenty of error like this : Failed to connect to database: Error: Access denied for user: ´[EMAIL PROTECTED]´ to database ´DB1´ MySQL server has gone away Error Nø1, please contact webmaster ... In fact, clients are C cgi compiled with libmysql ( in this package MySQL-devel-3.23.49-1.i386.rpm ) The Cgi is ok and have worked well since several mounths. Error Nø1 : connection mysql ok, can't execute my query It seems that mysql disconnect me before i can execute my query. But query is just after the connection in the code ... :( Server : Linux Redhat 2 * PIII 1 Ghz 1Go ram Scsi raid 5 mysql-3.23.53a-pc-linux-gnu-i686.tar.gz ( binary ) As you can see, i connect to my server via a 100Mb LAN. The LAN is ok, all ethernet card are 100Mb Full Duplex without any collision or packet dropped. Exemple : RX packets:259950587 errors:0 dropped:0 overruns:0 frame:0 TX packets:1809122347 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 lg file transmission:100 RX bytes:3130833186 (2985.7 Mb) TX bytes:1637489037 (1561.6 Mb) Here's the my.cnf : # The MySQL server [mysqld] port = 3306 socket = /tmp/mysql.sock skip-locking skip-name-resolve set-variable = key_buffer=256M set-variable = back_log=150 set-variable = record_buffer=1M set-variable = sort_buffer=1M set-variable = max_allowed_packet=1M set-variable = thread_stack=128K set-variable = max_connections=700 set-variable = max_connect_errors=100 set-variable = table_cache=512 set-variable = net_read_timeout=180 set-variable = net_write_timeout=180 set-variable = wait_timeout=3600 set-variable = thread_concurrency=4 I can't see anything in the error log.
