 Description   

Allow the MaxConns threshold to be above 20k, up until the OS limit of 65k. This is a significant problem among the PHP community, that has to run a separate PHP process for each concurrent access. With the absence of connection and thread pooling, it can easily occur that the 20k limit is hit.

Naturally, when this is changed, a warning should be printed to the user informing them of the dangers of raising the number too high. I.E. about 1 gig of memory used for every 1k connections.
