[syslog-ng]syslog-ng doesn't re-open the TCP connection

[Rosenberg, Relu (Exchange)]

This is syslog-ng 1.4.13 on Solaris 8, reading from named pipe and sending
over tcp to a central server syslog-ng.

Configuration file:

options {
        long_hostnames (on) ;
        use_dns (no) ;
        use_fqdn (yes) ;
        keep_hostname (yes) ;
        chain_hostnames (no) ;
	  log_fifo_size(1000) ;
        } ;

source s_pipe {
	pipe ("/tmp/.syslog-ng.pipe") ;
	internal () ;
	} ;

destination d_tcp {
        tcp (remote_host port(2222)) ;
        } ;

log {
        source (s_pipe) ;
        destination (d_tcp) ;
        } ;

In order not to replace the syslog I tail the /var/adm/messages and redirect
into the /tmp/.syslog-ng.pipe.
Syslog-ng is reading the pipe and sending to remote syslog-ng over tcp.

At a point in time it stopped sending messages, doesn't try to re-open the
lost TCP connection. The connection may have been lost due to network
outage or maintenance work, but it should reopen.
This happens to over 10 clients, I have over 300 working this way.


The truss output shows the read of new messages from named pipe, but no
attempt to write, or to re-open the connection to the remote server

51/1:          poll(0xFFBEFB10, 2, 60000)                      = 1
351/1:          read(3, " M a y     7   1 8 : 2 8".., 1024)     = 70
351/1:          time()                                          = 1020810505
351/1:          time()                                          = 1020810505

351/1:          time()                                          = 1020810505
351/1:          poll(0xFFBEFB10, 2, 100)                        = 0
351/1:          poll(0xFFBEFB10, 2, 60000)      (sleeping...)
351/2:          signotifywait()                 (sleeping...)
351/3:          lwp_cond_wait(0xFF0F55B0, 0xFF0F55C0, 0xFF1F5C48)
