My server returning an error sth. like swap = 0 then locking httpd and all
Set up a monitoring tool like sar etc. or my favourite, nmon with capacity planning. Depending on what those 4k users are doing, you might be running out of RAM + swap space until the out-of-memory killer kicks in and frees up some space by killing some processes. You should be able to see that activity in the message logfile.
