Here's my.cnf:
[mysqld]
innodb_data_file_path = data/data1:2000M;data/data2:2000M
innodb_data_home_dir = /servers/mysql/
set-variable = innodb_mirrored_log_groups=1
innodb_log_group_home_dir = /servers/mysql/data/logs/
set-variable = innodb_log_files_in_group=3
set-variable = innodb_log_file_size=50M
set-variable = innodb_log_buffer_size=20M
innodb_flush_log_at_trx_commit=0
innodb_log_arch_dir = /servers/mysql/data/logs/
innodb_log_archive=0
set-variable = innodb_buffer_pool_size=50M
set-variable = innodb_additional_mem_pool_size=20M
set-variable = innodb_file_io_threads=4
set-variable = innodb_lock_wait_timeout=50
innodb_flush_method=O_DSYNC
This problem arose before the installation of PostGres. Even then I could not reserve
more than 50M for innodb_buffer_pool_size.
The only thing that is also running on the machine is a HTTP server that uses at most
60M of mem.
