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?

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.
