Re: [K12OSN] Random logouts, inability to log in

Dear Folks,
	would you please take a look at the memory usage on your servers?
I have downgraded a server to 3.1.2 with the effect of using about *half*
the memory as with 4.0.0, same job mix, same users. Is this just me, or is
there something unwholesome about the Fedora Core based system. Take a
look:
v.3.1.2:
 10:17:37  up 19:13, 21 users,  load average: 0.01, 0.07, 0.07
517 processes: 516 sleeping, 1 running, 0 zombie, 0 stopped
CPU0 states:   1.0% user   1.1% system    0.0% nice   0.0% iowait  97.2%
idle
CPU1 states:   0.5% user   0.1% system    0.0% nice   0.0% iowait  98.4%
idle
CPU2 states:   0.4% user   0.4% system    0.0% nice   0.0% iowait  98.2%
idle
CPU3 states:   0.3% user   0.4% system    0.0% nice   0.0% iowait  98.3%
idle
Mem:  3870568k av, 2171984k used, 1698584k free,       0k shrd,  488268k
buff

v.4.0.0 with 9 users, memory usage same as with 20 users:
