I am running 2.4.18-3. I am getting terrible performance. I noticed in the boot.log that my / fs is ext3 and my kernel does not support ext3. I have tried to recompile the kernel with ext3 support. It did not seem to work. (e.g. lags for 40 or so when i am unzipping multiple files) Firstly, is this likely to be the case of my problems? How can i fix it? Do I just recompile the kernel or do I need

...system running several (I think) Seagate 80gig SATA drives. I tried to copy data from the first drive (sda) to the second drive (sdc) and was only getting about 1.7megs/sec. So I figured DMA was off. And this is what happened when I typed "hdparm -d1 /dev/hdc": /dev/hdc: setting using_dma to 1 (on) HDIO_SET_DMA failed: Operation not permitted using_dma = 0 (off) Any suggestions? I've never had this type of problem before. Thanks,

I also experienced this problem and the first thing that really helped out was changing the timing in the span line of the zaptel.conf. Change it to look like this (see below) and see if it helps out. I got the error much less after doing this and eventually got rid of the error completely by removing my raid drives, installing an IDE drive, enabling DMA mode on the Hard Drive, enabling APCI in

Hello Folks, We have 2 (identical hardware) busy public 2U rack servers, both have several hundred users & peak email (for example) deliveries at 300/5min during the daytime. Both servers run RAID1 over 2 EIDE disk drives. One server is fine - it never has problems - it is running RH7.3 and CPU loads are normal. The other server has constant disk activity & kjournald at CPU load of

Hi, I'm running into issues receiving faxes which, from what I have read, may be caused by frame slips. While I can find many posts saying to investigate it, I can't find any that describe *how* to debug the problem. Tried searching this list as well to no avail. Any pointers would be greatly appreciated. FYI, I'm running wbel, AMP 1.04, spandsp 2pre4. Faxing to a pstn on a
