Whole system repeatedly freezing for a second under high cpu load (with UDMA!)
Hi (sorry for my mailing problems), on my system I run donkey_v59-4-gaps by ed2k_gui with nice (10). After launching checks or re-creates md5 hash keys of all shared files (here many big films). You can then hear donkey accessing the disk and regularly making short pauses (ca. 1 s) - while the whole system does nothing (I suppose): no mouse movement (but it "remembers" your input), even the transfer while copying files pauses. WHY?! My System: Duron 950 with 768 MB RAM on EPOX 8TKA3 (VIA 686B) Disk in question Maxtor 80 GB 7200 UPM at PM-Onboard UDMA5 Partitions with films ext3 resp. vfat (Plextor 241040TA UDMA2 at SM-Onboard - not mounted) (Promise Utra 100 TX2 with 2. disk) (IBM 40 GB 7200 UPM at PM-Promise UDMA5 - System on RAID-0) (Pioneer DVD at SM-Promise UDMA4 - not mounted) SuSE-Linux 8.1 with 2.4.20-vanilla (with TIOCGDEV patch which I think doesn't do anything, and lm_sensors/i2c_modules (don't work either, but no errors: sensors just don't find anything) and nvidia module (works fine) (I think I'll be going to write another mail soon about the problem that while copying a film from vfat to vfat on another partiton on the same harddisk - maybe relatively strongly fragmented - I only get transfer rates of 0.8 MB/s average. This is to slow, isn't it?!? Maybe all this has to do with each other.)

MIGHT be a DNS problem. Do you have a specific task that freezes the thing? Or is it a random thing? Those short hickups tend to be something waiting for something else -- /Rikard ------------------------------------------------------------------------------------ Rikard Johnels email : rjhn@linux.nu Web : http://www.rikjoh.com Mob : +46 70 464 99 39 ------------------------ Public PGP fingerprint ---------------------------- < 15 28 DF 78 67 98 B2 16 1F D3 FD C5 59 D4 B6 78 46 1C EE 56 >
