# Known Issues
|
||||
|
||||
There are a number bugs and known limitations within this version of MaxScale, the most serious of this are listed below.
|
||||
|
||||
* The Read/Write Splitter is a little too strict when it receives errors from slave servers during execution of session commands. This can result in sessions being terminated in situation in which MaxScale could recover without terminating the sessions.
|
||||
|
||||
* MaxScale can not manage authentication that uses wildcard matching in hostnames in the mysql.user table of the backend database. The only wildcards that can be used are in IP address entries.
|
||||
|
||||
* When users have different passwords based on the host from which they connect MaxScale is unable to determine which password it should use to connect to the backend database. This results in failed connections and unusable usernames in MaxScale.
|
||||
|
||||
# Packaging

||||

||||
Both RPM and Debian packages are available for MaxScale in addition to the tar based releases previously distributed we now provide

# MaxScale Home Default Value
|
||||
|
||||
The installation assumes that the default value for the environment variable MAXSCALE_HOME is set to /usr/local/skysql/maxscale. This is hard coded in the service startup file that is placed in /etc/init.d/maxscale by the installation process.
