Its more a question of how/why it is stopped... If you have a program/script to stop the daemon then just add a line so it adds when it was stopped... if its because of ??? Then you have no other choice either to use a monitoring utility ( e.g. opensource nagios ?) or write your own and scheduling it correctly so it doesnt take too much resource...
If you log when it starts while at it keep also its PID, then you know what to look for...

rpc.statd
RPC.STATD(8) BSD System Manager's Manual RPC.STATD(8)
NAME
rpc.statd -- host status monitoring daemon
SYNOPSIS
rpc.statd [-d]
DESCRIPTION
rpc.statd is a daemon which co-operates with rpc.statd daemons on other hosts to provide a status monitoring service. The daemon accepts
requests from programs running on the local host (typically, rpc.lockd(8), the NFS file locking daemon) to monitor the status of specified
hosts. If a monitored host crashes and restarts, the remote daemon will notify the local daemon, which in turn will notify the local pro-
gram(s) which requested the monitoring service. Conversely, if this host crashes and restarts, when rpc.statd restarts, it will notify all
of the hosts which were being monitored at the time of the crash.
Options and operands available for rpc.statd :
-d The -d option causes debugging information to be written to syslog, recording all RPC transactions to the daemon. These messages are
logged with level LOG_DEBUG and facility LOG_DAEMON. Error conditions are logged irrespective of this option, using level LOG_ERR.
The rpc.statd daemon must NOT be invoked by inetd(8) because the protocol assumes that the daemon will run from system start time. Instead,
it should be configured in rc.conf(5) to run at system startup.
FILES
/var/db/statd.status non-volatile record of currently monitored hosts.
/usr/include/rpcsvc/sm_inter.x RPC protocol specification used by local applications to register monitoring requests.
SEE ALSO
syslog(3), rc.conf(5), rpc.lockd(8)
STANDARDS
The implementation is based on the specification in X/Open CAE Specification C218, "Protocols for X/Open PC Interworking: XNFS, Issue 4",
ISBN 1 872630 66 9
HISTORY
A version of rpc.statd appeared in SunOS 4.
BUGS
There is no means for the daemon to tell when a monitored host has disappeared permanently (e.g., catastrophic hardware failure), as opposed
to transient failure of the host or an intermediate router. At present, it will retry notification attempts at frequent intervals for 10
minutes, then hourly, and finally gives up after 24 hours.
The protocol requires that symmetric monitor requests are made to both the local and remote daemon in order to establish a monitored rela-
tionship. This is convenient for the NFS locking protocol, but probably reduces the usefulness of the monitoring system for other applica-
tions.
The current implementation uses more than 1Kbyte per monitored host in the status file (and also in VM). This may be inefficient for NFS
servers with large numbers of clients.
