Hi I have a box that is a Linux LVS project based load balancer running on an 1850 and x86_64 bit version of CentOS. In the past i have never had issues with LVS but then again i have never tried it with x86_64 linux. This box will after a variable about of time, 1 day upto a week or so, stop accepting ssh connections, although http connections will be fine, and then after another period of time http will also stop being accepted/forwarded. It remains pingable but the only option is a power cycle. There is nothing in the logs as to why and this box was doing this when it was a 4.2 machine but it has recently been updated to 4.3 but the issue remains. There is nothing obvious in any logs and i can run x84_64 happily on other 1850's although they are not LVS's. The only thing that is showing up in the logs is this (scsi0:A:6:0): data overrun detected in Data-in phase. Tag == 0x3. (scsi0:A:6:0): Have seen Data Phase. Length = 50. NumSGs = 1. sg[0] - Addr 0x030910000 : Length 50(scsi0:A:6:0): data overrun detected repeated lots - does anyone know what that might be but also what could be the cause of this? thanks
