When running a caching webproxy on the excellent RB951G [1] with RouterOS 6.2, when the cache starts filling up (eg 1GB of data), I see a significant rate of ‘connection reset by peer’ messages in browsing sessions, around 5-10% of the time. This affects HTTP GETs, but worse HTTP POST, so form information/state has to be reentered. Disabling the transparent port 80 redirect rule prevents this, but then disables proxying.
I downgraded to RouterOS 6.1 and can reproduce it there, and with multiple USB sticks/disks and clients. Any ideas?
Many thanks,
Daniel
