Dear Bharat,
1. I have tested on three OS Env
>Win XP
>Solaris 10
>SuSE Linux (on ATCA)
2. Yes, on windows the behavior is not- alarming. Its stable. But solaris
and Linux shows a memory Increase, as i have explained in the prev Post.
3. I have used JConsole and rational Purify to monitor the
Heap/non-heap/Perm Generations of Memory.
"prstat" utility was used on Solaris to observe the memory claimed by the
process.Also "pmap"
4. <i>//The memory of the server continously increases from ~90M to ~350M
which
never comes down.
How did you check this?</i>
At startup prstat gives a value around 80M Resident Memory and total Mem
164M. After the load testing (around 800,000 continuous requests) the value
goes very high, ie 325M RSS and 388M Total Memory.
At the same time Heap shows negligible increase after GC, as i have shown in
the table.
One word about the table:
Table has the following columns
> Total Mem as shown in prstat
> RSS Mem as shown in prstat
eg:
PID USERNAME SIZE RSS STATE PRI NICE TIME CPU PROCESS/NLWP
3769 root 207M 124M sleep 59 0 0:02:09 4.4% java/40
and..
>Used
>Commited
>Maximum allowed
Memory as per JConsole of JDK 5
And the RSS and total mem used for the process never goes down from the high
value even after GC (but this is the behavior of process on Solaris ?)
5. This memory Increase happens only in HTTP transport. in JMS its fine, as
Hubert observed.
6. I can send the pmap dump and other details, if required.
