I have been trying to use alh and am getting sporadic (every 2-3 hours) CA
disconnect of groups of records.  The alh config file has records in two
IOC's.  When a disconnect occurs,  all records attached to an IOC disconnect
and then reconnect the next second.  This happens to both IOC but not at the
same time.

The system is lightly loaded.  The TMO variable is 30 seconds and the BEACON
is 15 seconds.  medm clients and other CA clients on the host do not
disconnect.  This behavior been the case with the latest alh(1.1.2) and a
former version.

The error message I get is shown below (one message for each
mass-disconnect, not one for each record).  The transient PV alarm states
are  COMM and INVALID,  and then back to NO_ALARM again the next second.

Using R3.13.0beta11, mv177 IOC, solaris Host.  "Private" network.  Any
clues?
