reboot everyday ?

vacilus · 04-15-2005, 02:53 AM

hello to everyone,

I have 2 RH Servers that run bacula backup program scheduled.
Every night at 04.00 each server make an hard backup operation for another network pcs and the servers's performance drastic change :
mem. from 25% --> 95% !!!!

for my opinion is the bacula process taht required too many memory .

my question is :
is there a method for free memory that was allocated but now isn't used ?
or (2° possibility) I must reboot automatically the server every night for mantain free memory ??

thank in advance ,
marco

I think your solutions of trying to free up memory or rebooting the machines are wrong.

If there is a problem with an application, fix it or replace it. Don't run another process to attempt to patch things on the backend of a process. It's not maintainable or successful.

Are you sure the memory goes up that high?

Here is a post where I explained to someone else with a similar situation:

Basically, it is probably buffers and cache in your memory which are moved out of the way as soon as something else is needed.

see this is what's so confusing about this post
memory looking used in a certain utility doesn't have anything to do with performance

has the performance drastically changed really and if so how ?

thanks for your reply, for a complete set of info:
it is not the performance of machine to increase, but the RAM memory (foo_bar_foo)
the procesess is a bacula process that starts every night at xx.xx for make
a mail backup from the mail servers. this operation takes 10 minutes of works,
and after the mem is climb-up.
I think cause of this situation maybe :
size of mail files that aren't small.
