Some time ago we opened a ticket for Liferay Portal 6.0 EE regarding a memory leak with the Dockbar and IE7. The memory consumption of the iexplore process gradually increases while browsing around Liferay. Evenually the system became unresponsive.

We are noticing similar behavior in Liferay 6.1 and Internet Explorer 8.0. For instance, browsing Liferay 6.0 EE SP1 uses around 60 MB's of memory. Browsing the same pages in Liferay 6.1 causes Internet Explorer to use around 160 MB's.

The fix for Liferay 6.0 EE was a patch that came as a part of AUI-249. I am wondering if a similar fix is needed for Liferay 6.1?

Heya Bruno,
Can you take a look at this one?

Thanks,

Jamie,

Can you give me more information on how did you find this memory leak issue? What tools did you use? What were the portlets instantiated during your tests?

Thank you,

Bruno,

What we figured out is that the new Document Library uses around 160 MB's of memory on the system. Which I believe is normal because of the amount of Javascript in the new UI. The issue I was referring to actually caused the system to leak until it became completely unresponsive.

This ended up not being the same issue. Feel free to close this ticket.

Thanks,
Jamie
