Description Stephan Augustin 2008-04-24 06:48:26 UTC
during my backup, rsync exits without finishing its job. i've upgraded rsync to version 302, and debugged rsync with the rsync-debug script. 
Here is the output from the last run: 

fstat(3, {st_mode=S_IFREG|0644, st_size=38452, ...}) = 0
read(3, "\37\213\10\0\327\316\17H\0\3\354]\331r\333H\262}\266\277"..., 38452) = 38452
select(2, NULL, [1], [1], {60, 0})      = 1 (out [1], left {60, 0})
write(1, "\374\17\0\7", 4)              = -1 EPIPE (Broken pipe)
--- SIGPIPE (Broken pipe) @ 0 (0) ---
write(2, "rsync: writefd_unbuffered failed"..., 76rsync: writefd_unbuffered failed to write 4 bytes [sender]: Broken pipe (32)) = 76
write(2, "\n", 1
)                       = 1
rt_sigaction(SIGUSR1, {SIG_IGN}, NULL, 8) = 0
rt_sigaction(SIGUSR2, {SIG_IGN}, NULL, 8) = 0
write(2, "rsync error: error in rsync prot"..., 87rsync error: error in rsync protocol data stream (code 12) at io.c(1543) [sender=3.0.2]) = 87
write(2, "\n", 1
)                       = 1
select(0, NULL, NULL, NULL, {0, 100000}) = 0 (Timeout)
exit_group(12)                          = ?

during further Tests, I encountered that it always broke during tranzferring gzipped mysql-database-files ... afair, this is already known as bug ? 
Comment 2 Wayne Davison 2008-06-29 22:46:06 UTC
Your strace just shows that rsync tried to send some data to the remote rsync, and that pipe failed.  So, the important thing to discover is why the remote rsync went away.  So, get that strace output and it should reveal what is going wrong.

Rsync shouldn't fail transferring any kind of file, gzipped or not.

The bug might have been one of the recently fixed issues.  If you see any more problems, please let me know.
