Hi All,
I have been receiving "RED" EWA report for pure JAVA stack from past 3 weeks. Earlier also I had got it and then the heap memory size was 1024. I had increased to 3GB and then I started getting a "YELLO" EWA report alert. However, from past 3 weeks I have been getting a red EWA report for full Garbage Collection problem.
I had gone throug some of the threads here and found some usefule info like, Paul mentioned in below link:
[EWA Alert A- high ratio of garbage collection|;
How have gone to th dev_server0 file and saw some of the garbage collections there. I am quite unable to get the details mentioned there like:
1.
Mon Dec 12 07:43:12 2011
796020.432: [GC 796020.432: [ParNew: 319604K->28169K(320128K),
0.0588451 secs] 2671315K->2382219K(3116672K), 0.0589239 secs]

[Unloading class sun.reflect.GeneratedSerializationConstructorAccessor150]
[Unloading class sun.reflect.GeneratedMethodAccessor543]
[Unloading class sun.reflect.GeneratedSerializationConstructorAccessor220]......
I think the first one is the small garbage collections and the latter one is the "Full GC" as the name itself says.---Correct me if I am wrong.
Can any one help me in understanding the above details?
What should I do to remove this from my EWA alert?
Regards,
Faisal
Hi,
I have gone through the server nodes , std_server<n>.out (I have 3 server nodes) and found that on today's date, there are Full GC written in the logs multiple times. But can any one help me in diagnosing this and reaching out to the cause of this problem?
Regards
Faisal
