guest was dissapear but registered user still

[geevest.com]

For example,
in my forum there is currently active users : 800 ( 300 members and 500 guest)
and some times,after i do a refresh my site, iam not sure for the
time, teh guest visitors go down as drastic
become 202 ( 200 members and 2 guest) ( the numbers of the guest is
not always 1 or 2, but under 10).
but it will increase again as slowly..the number will go up again for
slowly like this 300 ( 260 members and 40 guest),
360 ( 300 members and 60 guest), slowly but it will up again as soon,
more and more..
but why just only for the guest that have to go down until that far?so
drastic numbers, but the members doesnt
change that much?
is this because of myn hosting mistake or there is something wrong
with my setting?

*i hope its my last question in my error.

Most likely the MySQL server was restarted.

PS I think you already asked the same question in another thread and it was also answered.

Guest sessions are only stored in an in-memory table which gets emptied when the MySQL server is restarted.

As said before - the MySQL daemon was probably restarted, which would have removed all sessions.

my hosting said their team never restarted my site at all.
but what happen is that my site always been restarted for twice / more.
but im still wondering in here,when the restarted happen the one thing it always change is the guest number.

so what i have to do.
