Hi! Rik,
Thanks for your help. I have successfully patched the kernel with your patches recompiled and installed it on my development system the hardware of which is identical to my Production machine (e.g. 8CPU, 8GB RAM)
I compiled the kernel with glibc-2.2.2-10 (redhat) I did some performance testing on my box by doing a full oracle dump and running some big java jobs. Well Kswapd now seems to be behaving....(thankfully!!)
When I do a top it shows me Mem: 8263740K av, 2967608K used, 5296132K free, 0K shrd, 6120K buff Swap: 2048248K av, 0K used, 2048248K free 2530948K cached
Now the cached part never gets freed and just keeps piling up & so does the used memory. On my production box with (kernel 2.4.13), both cached & memory used keet on increasing till it exhausts the entire physical RAM and the box falls over. It just doesn't swap.....(I thought with 8GB RAM I wouldnt need swap)
Anyways, then I updated the bdflush parameters....after that the memory does get reclaimed but only by a small percentage, so it hardly made any difference..Memory still keeps on piling up...forcing me to reboot the box everyday.
Do I need to make any changes to bdflush, freepages etc in /proc/sys/vm ??
Also, is it normal for linux to just keep on eating memory even though most of the processes are sleeping and not reclaim memory till the physical RAM is exhausted
Once, again I thank you for your response and assistance. I really look forward to hearing from you again!!
Best regards, Anish Srivastava
