Re: Swap fscked in 2.4.5?
To all experiencing the 2.4.5 swap problems, you guys should follow the kernel lists or read kernel-traffic when running the latest kernels. IIRC, shortly after kernel 2.4.5 was released there was a report of problems involving swap and memory use. The fix was to have twice as much swap as RAM (or more). This may require one to have multiple swap partitions, if you have more than 64M of RAM. If you have more than one HD and your machine is using swap, you can improve your machine's performance by placing each swap partition on a different drive. I tested this on a machine running 2.4.5 and found that it works fine, but I am not currently running that kernel, as I have no specific need for it. --ptw -- Paul T Wright [EMAIL PROTECTED] And, strange to tell, among the Earthen Lot Some could articulate, while others not: And suddenly one more impatient cried -- Who is the Potter, pray, and who the Pot? -- The Rubaiyat of Omar Khayyam --

Swap fscked in 2.4.5?
My swap partition is behaving very rudely. Specifically, swap space never seems to get freed- swap size only increases, never decreases. Once it maxes out, the system becomes sluggish, and there's nothing to do but reboot (the notion of rebooting a system to fix a problem is giving me Windows flashbacks...)

I'm told that this is a bug in the 2.4 series- does anyone know if upgrading to 2.4.6 will help this problem at all? I've not monitored swap usage since upgrading to 2.4.6 so I cannot answer that. If not, are there any other workarounds? How much swap RAM do you have? I've heard (on kernel mailing list IIRC) that if your swap is 2-3 * RAM size, the bug shouldn't hurt anything. I've less swap then RAM here, and I get out of memory errors after about 2 weeks uptime. AFAIK known workarounds are to have plenty of swap or to reboot the box every once in a while.

Re: Swap fscked in 2.4.5?
I try to clean up the swap once in a while after running big apps: swapoff -a and then swapon -a. Note that while you swapoff, if you run X, it might freeze up for the duration of the execution (however, it unfreezes once swapping is done). Andrei -- First there was Explorer...

Ther's no more 128M size limit on swap partitions with 2.4.x. I'm sure there's a limit on the size of a swap partition but I've got a 2G one and, other than apparently never freeing itself, it's been used right up to the 2G size. Gary
