Hi list, since we activated 10gbe on ixgbe cards + jumbo frames(9k) on 9.0 and now on 9.1 we recognize that after a random period of time, sometimes a week, sometimes only a day, the system doesn't send any packets out. The phenomenon is that you can't login via ssh, nfs and istgt is not operative. Yet you can login on the console and execute commands. A clean shutdown isn't possible

I'm transferring 1.1 Mb files over very poor GSM EDGE connection. My rsync command is: rsync --partial --remove-source-files --timeout=120 --append --progress --rsh=ssh -z LOCAL_FILE root at SERVER:REMOTE_PATH File on remote server "grows" in size in steps of 262144 bytes. That is a lot, because system needs to transfer at least 262144 (before compression) every time connection is established. When I use scp --C chunk size is about 32Kb. Is there a way to change chunk size for rsync? I use rsync 3.0.7. -- Regards, Marcin Polkowski Zak?ad Fizyki Litosf...
