On loghost as log store I'm using syslog-ng-1.6.5-2 + mysql-4.0.21-4. OS is Suse-9.2. After configuring database and syslog-ng.conf and start script which send logs to mysql from FIFO, I see the following mysql error : ERROR 1040: Too many connections. Part of syslog-ng.conf where the only local log send to FIFO: destination d_mysql_local { pipe("/var/log/mysql.pipe" template("INSERT INTO logs (host, facility, priority, level, tag, datetime, program, msg) VALUES ( '$HOST', '$FACILITY', '$PRIORITY', '$LEVEL', '$TAG', '$YEAR-$MONTH-$DAY $HOUR:$MIN: $SEC', '$PROGRAM', '$MSG' );\n") template-escape(yes)); }; log { source(src); destination(d_mysql_local); }; Loghost have about 10-20 local log messages per minute. Database use only for syslog queries and the load of server CPU about 10% . Script which sends log from FIFO to Mysql : #!/bin/bash if [ -e /var/log/mysql.pipe ]; then while [ -e /var/log/mysql.pipe ] do mysql -u syslog --password=secret syslog < /var/log/mysql.pipe done else mkfifo /var/log/mysql.pipe fi server:/bin # ls -la /var/log/mysql.pipe prw------- 1 root root 0 2005-03-23 12:53 /var/log/mysql.pipe I try to increase max_connection to 500 but this don't solve the problem. Have anyone the same problems? I have the same installation on FreeBSD-5.3p5 and have no problems.
