I've tried using 64 as max_interrupt_work and it solves completely the e401 problem on this particular machine : - yoda.rez-gif.supelec.fr (dns/proxy for 500 clients, on a 10Mbits/s direct Internet connexion, local network is 100Mbits/s) ASUS P2B-DS dual PII-350 512MB RAM (2*128+1*256) 3*IBM 18GB 10KT U2W SCSI 3C905C S3 Virge Linux Slackware-current, 2.2.19 or 2.4.4 both built for smp with APIC. Before setting max_interrupt_work at 64, the e401 error could occur 20 times a day. Now it doesn't occur anymore. I have waited for a long time to test that on the SMP PC because it is critical for our network. I have tried to link these e401 messages with another activity on the PC, like heavy I/O, to no avail. The 3C905C does 10 times as many interruptions as the SCSI controller does. Lowering the max_interrupt_work creates a lot more errors in the logs (all are e401). On that second PC, the message still appears (very rarely though, about once in two or three days. I cannot relate those occurences to anything). It used to appear very often (about 40 times a day). I have tried to put the machine under stress (4 heavy FTP transfers at once, each 400MB long, with 4 different clients, connected in 100 MBits FD). The e401 message has not appeared... I'm a bit at a loss here. - lando.rez-gif.supelec.fr (FTP for the same network) ABIT LX6 PII300 128MB RAM IBM 8.4GB IDE (1st Master) + Maxtor 60GB IDE (2nd Master) 3C905C S3 Virge Linux Slackware-current, 2.4.4, ProFTPD All our network is 100MBits Full Duplex, switched with 3COM switches.
