Hi.

I have cipe 1.5.2 (updated with last patch) on RedHat Linux 6.2
(kernel  2.2.19-6.2.7) and I'm using ipchains.

I have 1 central site a 5 remote sites.

All runs OK, but since a couple of days I began to have this
message in the log of the central site:

Feb  8 16:13:37 cipe ciped-cb[17989]: kxchg: recv: Connection refused

Feb  8 16:13:37 cipe kernel: cipcb: cipe_unalloc_dev 3

After that I lose the link with this site. 

Any idea or advice will be very appreciated.

ifconfig output in central site is:
 
(all interfaces are in 192.168.x.x networks, since I'm using
 private links, between the sites)
