10048: Maximum number of connections
Quote:
We recommend that you modify the maximum number of connections in the my. ini file,
Change the mysql_connect () method to the mysql_pconnect () method.
To modify mysql_pconnect (), you can go to SQL _config.php in the data directory of the Forum.
$ Pconnect = 0; // whether the connection is persistent
Change to $ pconnect = 1;
Enable anti-Refresh. Do not refresh too quickly.

10055: no cache space available

Check whether your drive C is full and clear useless files.
You can enable "Process Optimization" in "Forum core Settings", "core function Settings", and "gzip compressed output" in the background.
I found the cause of the error 10055 (no cache space available) and analyzed the preparation file of my. ini,
In my. ini:
Default-storage-engine = InnoDB
Innodb_additional_mem_pool_size = 2 M
Innodb_flush_log_at_trx_commit = 1
Innodb_log_buffer_size = 1 M
Innodb_buffer_pool_size = 10 M
Innodb_log_file_size = 10 M
Innodb_thread_concurrency = 8
I think we can increase innodb_buffer_pool_size = 10 M, for example, 1000 M or M.
The above is for mysql5

For mysql4, you can add the following in my. ini:
# Innodb_data_file_path = ibdata1: 2000 M; ibdata2: 2000 M
# Innodb_data_home_dir = C: ibdata
# Innodb_log_group_home_dir = C: iblogs
# Innodb_log_arch_dir = C: iblogs
# Set-variable = innodb_mirrored_log_groups = 1
# Set-variable = innodb_log_files_in_group = 3
# Set-variable = innodb_log_file_size = 5 M
# Set-variable = innodb_log_buffer_size = 8 M
# Innodb_flush_log_at_trx_commit = 1
# Innodb_log_archive = 0
# Set-variable = innodb_buffer_pool_size = 16 M
# Set-variable = innodb_additional_mem_pool_size = 2 M
# Set-variable = innodb_file_io_threads = 4
# Set-variable = innodb_lock_wait_timeout = 50

10061: MySQL service cannot be started normally
Quote:
Start the MySQL service on this machine
If the service fails to be started, it must have been an error in your my. ini file. The MySQL service cannot be started normally.
After you delete it, MySQL will run according to its default configuration, so there is no problem.
