Subject RE: [users@httpd] Max number of connections from a single client to a server.
Date Tue, 10 Jan 2006 10:58:19 GMT
 After re-reading the original post, I observe the mention of "from a single client".

There is nothing that limits the number of connections from any particular client.

There are several parameters that determine the maximum number of connections.
Only one of them is an Apache parameter: MaxClients.
In addition to this, there are system limits that restrict the number of connections a single
process may accept. If you use the worker MPM of Apache 2.x, the maximum number of file descriptors
that can be opened by a single process may be a factor, especially for a proxy. 

You can browse or set that limit using "ulimit -n" on Unices. Kernel parameters define a "hard"
limit that cannot be exceeded, as well as a default "soft" limit. In Solaris those are rlim_fd_max
and rlim_fd_cur. In Linux those parameters are set in the /proc file system (I believe it
is /proc/sys/fs/file-max).
