rsync problems

[Michael W. Lucas]

Hi,

I'm hoping someone can help me with an rsync issue.

I have an old rsync client (version 2.3.1) on an effectively embedded
SunOS system. Changing the client is not an option, it's part of a
great big multimillion-dollar telephony system.

Until last Thursday, I was successfully rsyncing to a FreeBSD machine
using rsyncd. Then I rebooted it. Now rsync requests fail with:

Mar 17 16:20:22 cdrbucket2 rsyncd[1003]: rsync error: error in rsync protocol data stream (code 12) at io.c(226) [Receiver=3.1.0]
Mar 17 16:21:43 cdrbucket2 rsyncd[947]: rsync error: received SIGINT, SIGTERM, or SIGHUP (code 20) at rsync.c(632) [Receiver=3.1.0]

This is not a helpful message. Rsync is not known for helpful error
messages, so I tried truss. Here's the notable section of the output:

...
 1003: open("/etc/group",O_CLOEXEC,0666)         = 4 (0x4)
 1003: fstat(4,{ mode=-rw-r--r-- ,inode=4127,size=503,blksize=4096 }) = 0 (0x0)
 1003: lseek(4,0x0,SEEK_CUR)                     = 0 (0x0)
 1003: lseek(4,0x0,SEEK_SET)                     = 0 (0x0)
 1003: read(4,"# $FreeBSD: release/10.0.0/etc/g"...,4096) = 503 (0x1f7)
 1003: close(4)                                  = 0 (0x0)
 1003: chroot("/cdr/telicavoip")                 = 0 (0x0)
 1003: chdir("/")                                = 0 (0x0)
 1003: process exit, rval = 12
  947: select(6,{4 5},0x0,0x0,0x0)               ERR#4 'Interrupted system call'
  947: SIGNAL 20 (SIGCHLD)
  947: wait4(-1,0x0,WNOHANG,0x0)                 = 1003 (0x3eb)
  947: wait4(-1,0x0,WNOHANG,0x0)                 ERR#10 'No child processes'
  947: sigreturn(0x7fffffffae50,0x0,0xffffffffffffffff,0x0,0x0,0x8014001b0) ERR#4 'Interrupted system call'

Any way to tell what child process it might be expecting, or where
it's hanging up here?

Thanks for any hints,
==ml
