Good day KarthiK.P.R Other than the replication settings in '/etc/mysql/conf.d/replication.cnf' and our /etc/mysql/conf.d/custom.cnf
xyz-web02:/data# cat /etc/mysql/conf.d/custom.cnf [mysqld] innodb_file_per_table bind-address = 0.0.0.0 datadir = /data binlog_format=mixed key_buffer_size=8384512 max_connections=41 The original /etc/mysql/my.cnf is untouched. The only other service we have running is DRBD (active / active) and apache, nothing is hitting apache as this is the standby node. And there is no load, or anything consuming resources.

HI Brent, Can you please paste your configuration file settings (my.cnf) ? It will help to identify where things went wrong. Is there any other memory consuming application running on the server beyond mysql ?

We run Mysql replication, and on the second node, Mysql is crashing with 'mysqld got signal 6' every so often. Other than the drives, we have replaced the hardware, and still the problem persists. Googling, I thought it was a memory exhaustion issue, so I started playing with the following variables and values. key_buffer_size=8384512 max_connections=41 But it still crashes Mar 27 12:36:53 xyz-web02 mysqld: key_buffer_size=8384512 Mar 27 12:36:53 xyz-web02 mysqld: read_buffer_size=131072 Mar 27 12:36:53 xyz-web02 mysqld: max_used_connections=3 Mar 27 12:36:53 xyz-web02 mysqld: max_threads=41 Mar 27 12:36:53 xyz-web02 mysqld: thread_count=1 Mar 27 12:36:53 xyz-web02 mysqld: connection_count=1 Mar 27 12:36:53 xyz-web02 mysqld: It is possible that mysqld could use up to Mar 27 12:36:53 xyz-web02 mysqld: key_buffer_size + (read_buffer_size + sort_buffer_size)*max_threads = 97828 K bytes of memory xyz-web02:# free -m total used free shared buffers cached Mem: 12038 11966 71 0 117 11378 -/+ buffers/cache: 469 11568 Swap: 2047 0 2047 We running Debian Squeeze 64bit.
