strange tinc error with many nodes

Tue Dec 13 18:40:12 CET 2005

Hello,

we currently set up a large tinc network with 2 central Nodes (these nodes connecting to each other).

All satellites (ca 40) connect to these both machines.  All containing two ConntectTo fields (for backup)

e.g. (satellite)

Name = nfp_hy
Device = /dev/tun
PrivateKeyFile = /etc/tinc/nfp_hy/rsa_key.priv
ConnectTo = nfp_f_vpn
ConnectTo = nfp_c_vpn

If the count of satellites reaches 40, many strange error log entries are visible (but only in the log file of the 2nd central
box). if we lower the number of satellites that connecting to these two boxes the errors gone.

These error occurs an some satellites (less 3)

Dec 13 19:17:20 gt-fw-nfp-konstanz-scala last message repeated 7 times

And these are a short cut from the central box

The connection most times work. Tinc is 1.0.4 or 1.0.3 no difference between.

There are reasons for these interruptions? Do we something wrong?

Thanks in advance
