[SR-Users] DHCP renewal conflicts with kamailio?

[Joonas Harjumäki]

Hi!

The attachment contains a log trace of kamailio 3.3.2. There is some 
errors in the log and I wonder if it is normal operation?
The errors appeared in the middle of DHCP lease renewal and I wonder if 
the configuration (of dhclient/kamailio) could be improved to prevent 
such errors? Or to make sure kamailio retries udp_send sufficiently many 
times. The kamailio operated normally before renewal procedure began and 
after the procedure finished.
