I am currently having difficulties tracking down a problem. We have two
servers, one of which has mySQL installed (3.23.40). Domains on either
server can opt to have a mySQL database, and there are a number of Dbs set
up. We have a relatively low number of maximum connections allowed, and some
users are getting an error because this limit is being reached.

It appears to be down to one domain and their database, but I cannot see why
it is happening. This is what we have:

Server1 without mySQL
Server2 with mySQL and phpMyAdmin

Among a number of domains on Server1 are two particular domains, which I'll
call Domain1 and Domain2. Domain1 has a Db on Server 2 and has a number of
scripts using php. Domain2 does not have a Db and does not use php.

If I go to phpMyAdmin on Server2 and select "show processes" this is the
sort of thing I get:

Id       User              Host      db              Command  Time  State
Info
3009  Domain1User Domain2 Domain1Db Sleep         284               NULL
3010  Domain1User Domain2 Domain1Db Sleep         266               NULL
3013  Domain1User Domain2 Domain1Db Sleep         242               NULL

3018  Domain1User Domain2 Domain1Db Sleep         135               NULL
3019  Domain1User Domain2 Domain1Db Sleep         123               NULL
3022  Domain1User Domain2 Domain1Db Sleep         46                 NULL
3023  Domain1User Domain2 Domain1Db Sleep         13                 NULL
3024  Domain1User Domain2 Domain1Db Sleep         10                 NULL
3028  root               localhost mysql         Query         0      NULL
SHOW PROCESSLIST

My questions are:

Why is Domain2 being shown as the host for these processes (the server name
is something entirely different)?
What could Domain1 have in their scripts that would be causing this (Their
main script is phpNuke)?
How do I increase the number of maximum users?
How do I reduce the length of time a connection will be kept open and
allowed to sleep?

Thanks for any help offered (and apologies for anyone for whom the above
table is way out of line)

Brian
