False Memory usage alarm!!

Hi Experts,

I am using Solaris-10, Sun-Fire-V445.

i got often the below message-

"Memory Usage – Critical, Memory usage (RAM) exceeding 90%
The memory utilization is exceeding 90%" in a application running on solaris.

I checked with Vmstat. Everything seems to be fine. Where i should check also? I already checked /var/adm/messages & /var/log/syslog.


Code:
 kthr      memory            page            disk          faults      cpu
 r b w   swap  free  re  mf pi po fr de sr s1 s2 s3 --   in   sy   cs us sy id

where are you getting the following error? Is it from the system itself or from your monitoring tool?
Memory Usage - Critical, Memory usage (RAM) exceeding 90%

in my monitoring tool. so far i checked there is no threshold defines in the monitoring tools.

Pls do verify with prtstat as well with process info and mem usage. It caould be a false alarm

Yes its a false alarm.

Any idea how do i fix this? do you think it is related with my monitoring tool?

else unix generate this false alarm?

What tool is this? What exactly is it measuring? Maybe the data segment of some process hit 90% of its max size. Or maybe the tool is broken.
