Run it and monitor the resources it consumes...I would not use trace as my first choice. I recommend using a tool like dbx to see what the process is doing or not doing. What o/s are you using? There are a number of other performance tools. I suppose the general choices of these tools is the monitor (like strace) or to look at the process state during hang. What analysis have you done when the process was hung?

scds_pmf_restart_fm
scds_pmf_restart_fm(3HA) Sun Cluster HA and Data Services scds_pmf_restart_fm(3HA)
NAME
scds_pmf_restart_fm - restart fault monitor using PMF
SYNOPSIS
cc [flags...] -I /usr/cluster/include file -L /usr/cluster/lib -l dsdev
#include <rgm/libdsdev.h>
scha_err_t scds_pmf_restart_fm(scds_handle_t handle, int instance
DESCRIPTION
The scds_pmf_restart_fm() function sends a SIGKILL signal to the fault monitor process tree to kill the fault monitor and then uses PMF to
restart it. This function uses the MONITOR_STOP_TIMEOUT property as its timeout value. That is, scds_pmf_restart_fm() waits at most the
value of the MONITOR_STOP_TIMEOUT property for the process tree to die.
If the MONITOR_STOP_TIMEOUT property is not explicitly set in the RTR file, the default timeout value is used.
One way to use this function is to call it in an UPDATE method to restart the monitor, possibly with new parameters.
PARAMETERS
The following parameters are supported:
handle The handle returned from scds_initialize()
instance For resources with multiple instances of the fault monitor, this integer, starting at 0, uniquely identifies the fault
monitor instance. For single instance fault monitors, use 0.
RETURN VALUES
The scds_pmf_restart_fm() function returns the following:
0 The function succeeded.
non-zero The function failed.
ERRORS
SCHA_ERR_NOERR Function succeeded
See scha_calls(3HA) for a description of other error codes.
