I have two Xeon 5160 Dual-Core 3,0 GHz on my box and 4Gb RAM. About 500k mail go through this MX (50Gb traffic). >What is the destination concurrency limit for mail heading to the >"kas-pipe" process? Right now it is set to 200. Well it was set to 40 before the problem appeared, but I increased it ... because I thought it was the problem. I don't know if lowering my concurrency limits would help. -- Viktor.
