we have a server with 8GB, running mysql, 4 java applications and a small postgres db.
can anyone tell me where the memory is gone:
(no, this time neither buffers nor cache)
# free
total used free shared buffers cached
Mem: 3928200 3868560 59640 0 2888 92924
-/+ buffers/cache: 3772748 155452
Swap: 4192956 226352 3966604
top, sorted by memory, descending:
top - 13:42:06 up 1 day, 3:47, 2 u
In my Ubuntu 11.10 VPS, Before I run the jar file:
# free -m
total used free shared buffers cached
Mem: 256 5 250 0 0 0
-/+ buffers/cache: 5 250
Swap: 0 0 0
Run a jar file that limited to maximum of 32M memory:
java -Xms8m -Xmx32m -jar ./my.jar
Now the memory
I have an issue where when I try to build a really large project, my machine starts swapping (several GB) even though there's plenty of memory (14 GB in fact).
A few days ago my linux apache server ran out of memory. The server is a xen guest. The server killed all my processes except ssh.
A minute before it ran out of memory, a script of mine saved the output of various commands.
i would like to get the value -/+ buffers/cache used who is 212, how can i do this?
i have free -m | grep -i mem | awk '{ print $2 }' for get value of total memory
total used free shared buffers cached
Mem: 7972 1237 6735 0 465 558
-/+ buffers/cache: 212 7760
Swap: 8001 0
I have two servers, server1 and server2. Both of them are identical HP blades, running the exact same OS (RHEL 5.5).
I have VPS server with 1.25GB ram and 0.51GB cache trying to up an e-commerce website with 200k items, db now is about 2gb anything is now works terrible slow now because of lack memory mysql queries takes about 30 seconds to complete on the peak memory usage.
