I have a Centos VPS that seems to have a lot of memory problems. First my hardware:
Processor Information Processor #1 Vendor: GenuineIntel Processor #1 Name: Intel(R) Xeon(R) CPU E5405 @ 2.00GHz Processor #1 speed: 198.721 MHz Processor #1 cache size: 6144 KB Processor #2 Vendor: GenuineIntel Processor #2 Name: Intel(R) Xeon(R) CPU E5405 @ 2.00GHz Processor #2 speed: 198.721 MHz Processor #2 cache size: 6144 KB Processor #3 Vendor: GenuineIntel Processor #3 Name: Intel(R) Xeon(R) CPU E5405 @ 2.00GHz Processor #3 speed: 198.721 MHz Processor #3 cache size: 6144 KB Processor #4 Vendor: GenuineIntel Processor #4 Name: Intel(R) Xeon(R) CPU E5405 @ 2.00GHz Processor #4 speed: 198.721 MHz Processor #4 cache size: 6144 KB Memory Information System Information Linux server.server777.ro 2.6.18-028stab060.2 #1 SMP Tue Jan 13 10:24:09 MSK 2009 x86_64 x86_64 x86_64 GNU/Linux Physical Disks Current Memory Usage total used free shared buffers cached Mem: 525312 426224 99088 0 0 0 -/+ buffers/cache: 426224 99088 Swap: 0 0 0 Total: 525312 426224 99088 Current Disk Usage Filesystem Size Used Avail Use% Mounted on /dev/vzfs 30G 13G 18G 44% / none 7.9G 4.0K 7.9G 1% /dev The memory seems to be generated by apache as the user nobody, on pages requests. The thing is that nothing on the code has changed. And i cant imagine what is causing this.
The websites hosted are not very popular, so there isnt so much trafic coming in.
How can i go about and diagnostic the problem. Thanks for any advice.
