Re: memory leaks?

Dmitry Samersoff — 2012-05-25T20:23:02

Ramki,

1. What version of 6u?? you tried.

2. We fixed couple of leaks related to JMX

e.g. 7066129 -
GarbageCollectorMXBean#getLastGcInfo leaks native memory

OK, that rules out the two native memory leaks that I fixed
earlier this year.

Hi Dan -- I don't believe either is being used in this case.

Re: memory leaks?

Daniel D. Daugherty — 2012-05-25T19:07:13

Hey Ramki!

Do you happen to know if java.lang.instrument, JVM/TI RedefineClasses()
or JVM/TI RetransformClasses() is being used by the system?

memory leaks?

Srinivas Ramakrishna — 2012-05-25T18:53:03

Just a quick question in case any one might remember off the top of their
head...

Are there any native memory leaks that may have been fixed in JDK 7 and 8
that haven't yet
been backported to JDK 6uXX?

No need for any research... just a quick check to see if anyone recalls
anything recently that
fixed native leaks... i'll go check the hg logs momentarily to see if
anything jumps out.

I am suspecting some 64 M segments that I see in pmap, and am yet to figure
out when and where
these are coming from... The leak is abrupt and likely the result of a
rather rare/infrequent event.
I'll see if I can find a DTrace that works on Linux and log mmap/munmap
calls to get more info.

thanks for any (even very vague) pointers.
