Subject: 3.12 ca repeater under solaris

Hello all,

Thanks to Kim Gillies, Bret Goodrich, and others at NOAO a
problem has been discovered in the 3.12 CA repeater under
solaris.

Symptoms:
Any one of the following symptoms occurring after many clients
have run on a particular solaris workstation:
o Solaris based CA client does not reconnect when the IOC reboots
o this message - 
../repeater.c: unable to connect client sock because "Bad filenumber"
o or this message
./repeater.c: unable to connect client sock

Cause:
Solaris implementation of the sockets API is not kernel based
and therefore does not process certain ICMP messages. This
resulted in the repeater not discovering that its clients
had disconnected. Eventually the repeater ran out of file 
descriptors.

A fix has been applied to epics_R3_12_2_patches and
epics_R3_13_0_alpha5.

Jeff
