I run FBSD 4.5-RELEASE and Apache 1.23 on a computer that provides services for web server, mail server, FTP server, DNS caching, name serving. The system has 1GB fast RAM with 1.4GB CPU and 1GB swap drive. The system is new with 2 40-Gig HDs and was developed to migrate over more than a dozen domains which has just been accomplished. It is a Tech site with about 10,000 visitors daily, downloading mostly html stuff, some occasionally streaming audio and book.pdf and ZIP files downloads. I notice the Hard Drive is rarely hit and the system does not seem to be laboring at all. It has 72 processes loaded, most all sleeping mostly. Shortly after, I moved the domains over, I started having crashes that seem directly related to my tar (gzip) backups which experienced no problems before. Figuring it had to do with tar's limits on >2GB file backups, I switched to gtar. Same crashing if not worse. I've had to disable my timed backups until I figure out what to do. Fsck so far has recovered my crashes, but after fixing a lot of problems on the HDs. The system is okay at the moment without the backups, but I NEED those backups! I'm just afraid to do it because of the inevitable hangs now. I know there are some sharp people on this list and I really need some ideas on this. I've thought of a bunch of things, but unsure of which. I even have two new HDs on the way to pull the others. BTW, when I installed those 40GB HDs, FBSD did complain about the geometry and I thought it would go forth and do its thing after FDISK, which it did and the system ran smoothly for the couple of months setting up for the migration. I did however notice on one of the crash reboots, HD-2 was not found in the BIOS. I had to go in and have it re-detected. The domains have added nearly 2GB of content and since the problems started after adding them, I wondered if tar (gtar) was somehow overwhelming the memory and/or system during the tar + compression activity during backup? How does tar + gzip do its thing? I figured it processed using RAM and swap and tmp... just a guess. Are there any ideas out there on this issue....??? Did I give enough info....??? .... our website: http://www.sage-one.net/ Best regards, Jack L.
