On SunOS 5.8 I get an error when starting a large Java process with over 2Gb memory.
When stopping several other Java processes we can start this process. This seems to indicate that we don't have enough consecutive memory blocks available.
top reports the following:
Thus even though we have 11Gb out of 32Gb free on our 6CPU system we can't allocate enough memory.
uptime reports:
Is it possible that the memory is too fragmented? How can we tell? or how can we fix this?

uptime
UPTIME(1) Linux User's Manual UPTIME(1)NAME
uptime - Tell how long the system has been running.
SYNOPSIS
uptime
uptime [-V]
DESCRIPTION
uptime gives a one line display of the following information. The current time, how long the system has been running, how many users are
currently logged on, and the system load averages for the past 1, 5, and 15 minutes.
This is the same information contained in the header line displayed by w(1).
System load averages is the average number of processes that are either in a runnable or uninterruptable state. A process in a runnable
state is either using the CPU or waiting to use the CPU. A process in uninterruptable state is waiting for some I/O access, eg waiting for
disk. The averages are taken over the three time intervals. Load averages are not normalized for the number of CPUs in a system, so a
load average of 1 means a single CPU system is loaded all the time while on a 4 CPU system it means it was idle 75% of the time.
