I have a question regarding a busy box I recently updated to
'2.4.2-ac20'. It has been running for several hours without any real
problems until I started getting 'dmesg' entries like:
Out of Memory: Killed process 30293 (httpd).
Out of Memory: Killed process 32552 (mysqld).
Not a quick check with 'top' shows:
Mem: 771440K av, 396060K used, 375380K free, 0K shrd, 4972K
buff
Swap: 379416K av, 345000K used, 34416K free 337128K
cached
I have also attached my "/proc/meminfo" & "/proc/slabinfo" details.
Basically they all show the server has 370MB of free physical memory but
its using lots of swap space and OOM is killing processes.
What gives?
Vince.

Maybe I should of also made it clear that is I run the same box with
2.2.18 I have no memory issues and swap is not used at all but when I
run with 2.4.2 I suddenly see my memory usage increase over 300MB and my
swap space maxes out.
