Sorry Venkatesh I was out on holiday for a few days. Probably a couple of factors at play:
- we are using weak/soft refs internally. Depending on how memory is being reported these may be shown in 'usage' stats but are really candidates for GC whenever the VM decides it wants to do so. - weavers exist for too many class loaders. This is the JSP discussion you referenced in the other thread. You mentioned the other thread but said you are using 1.7.3 which doesn't have the capability to exclude certain classloaders? You need the changes from a dev build if you want to try it, see the bug https://bugs.eclipse.org/bugs/show_bug.cgi?id=368046 that discusses the config options. A dev build containing the changes is here (AJ downloads page): aspectj-DEVELOPMENT-20130730075800.jar<http://www.eclipse.org/downloads/download.php?file=/tools/aspectj/dev/aspectj-DEVELOPMENT-20130730075800.jar> You might want to turn on the diagnostics so you can see which classloaders are getting weavers which will help you determine the names of those you'd like to exclude. cheers, Andy On 12 August 2013 23:38, Venkatesh Laguduva <lbvenkat...@gmail.com> wrote: > Experts, > Please do chime in with your thoughts. > > Thanks > Venkatesh Laguduva > > > On Sun, Aug 11, 2013 at 12:43 AM, Venkatesh Laguduva < > lbvenkat...@gmail.com> wrote: > >> We have enabled LTW in our web app as it is required for a library used; >> we are using the latest version 1.7.3 but unfortunately, as soon as I start >> the tomcat, I see that almost 50% of the heap is consumed by org.aspect.* >> objects. >> Class Name >> | Shallow Heap | Retained Heap | Percentage >> >> ----------------------------------------------------------------------------------------------------- >> org.apache.catalina.loader.WebappClassLoader @ 0x1794fcc0| >> 176 | 9,36,88,104 | 48.19% >> |- org.aspectj.weaver.ltw.LTWWorld @ 0x17941c78 >> | 136 | 7,65,52,016 | 39.37% >> | |- org.aspectj.weaver.World$TypeMap @ 0x17cc6cd0 >> | 40 | 7,64,98,456 | 39.35% >> >> ----------------------------------------------------------------------------------------------------- >> >> I could sense this post >> http://dev.eclipse.org/mhonarc/lists/aspectj-users/msg13940.html comes >> very close to my problem but did not help since I am already on the latest >> version. >> >> Thanks >> Venkatesh Laguduva >> > > > _______________________________________________ > aspectj-users mailing list > aspectj-users@eclipse.org > https://dev.eclipse.org/mailman/listinfo/aspectj-users > >
