Rsync 2.5.5; transfer via ssh; sparc-sun-solaris2.5 (Ultra 1); gcc 2.8.1. Every time rsync on this box causes boundary violation. I attached two strange examples. I have a few rsync's corefiles (100MB and above) and I can examine them. I will be grateful for any help. -Mirek <-------------------------------------------------------------------------> received 966761 names done

...QAContact: rsync-qa@samba.org If you use --iconv to sync between two machines and a file with a name that needs conversion is to be deleted, the rsync protocol may get out of sync and yield a protocol error if the converted filename differs in length form the unconverted name. This is because mplex_write in io.c will record and send the message length *before* the message has been converted using iconvbuf. If the converted message differs in length, the reading rsync process will get confused and interpret part of the message data as tag & length. Here is an example: [21:45:27]lenux:~/Mirro...

Hi all, today we had a performance issue transfering a big amount of data where one file was over 50GB. Rsync was tunneled over SSH and we expected the data to be synced within hours. However after over 10 hours the data is still not synced ... The sending box has rsync running with 60-80 % CPU load (2GHz Pentium 4) while the receiver is nearly idle. So far I had no acces to the poblematic
