Memory leak and Memory usage

[16年前 に fabio maggi によって更新されました。]

Hi All,

I have a serious problem in memory usage and memory leak,
also in last Liferay portal version,
liferay-portal-tomcat-6.0-4.3.5.

The problem is simply reproducible in Liferay 4.3.5 bundle with tomcat 6.0.
If I have 1000 (one thousand) events in calendar portlet in home page, all
in today date list,
when I execute login the memory usage in my machine is about 250 MB (4 user
= 1GB....),
and after logout there is a memory leak, about 20 MB, memory leak not always
reproducible.

The problem seems in Liferay Framework.

Have anyone a idea about this?
Do you know if same problems are reported?

Thanks for any suggestion.
Fabio

Are you sure it's not just the cache, or GC (Garbage Collection) has not
yet run?
Have you profiled this using a memory profiler?

We have used JProfiler and we have forced GC.
Which cache did you intend?

Thanks,
Fabio

Hibernate/ehcache?

Use JavaMelody to see the distribution of memory and other statistics with respect to traffic..than you can easily decide what to do next
