Your system time is rather high on this GC. Check the other long
GC's to see<br>
if there is similar high system times.<br>
<br>
8706.691: [GC 8706.691: [ParNew: 921599K->95151K(921600K),

sys=33.09, real=18.<br>

<br>
<br>
Something other than GC is likely contributing to these long pauses.<br>

<pre wrap="">Hello,
We performed load testing in our environment today and
there were 3 high par new times. There were no failure in
promotions and no full gc, the par new just took long on 7
occasions. The long times were: 4.1402018, 19.4847804,
18.2093573, 11.7687385, 3.8394909, 3.1041563 and 2.1444040.
The load test was ran for about 3 hours.
Any help would be appreciated. I'm attaching the
native_stdout.log. I'm also showing the jvm args below.

Any help would be appreciated.
Thanks,
