Bonjour a Tous,
I would like to know if more data has been collected on that
subject.
My application use libclamav, on the BOTH production system
under X86_64 a memory exhaustion is reported, while I32
got no trouble (E-mail usage volume beeing roughly the same).
Trouble are noticed on X86_64, CentOS release 4.4 (Final)
and Fedora Core release 6 (Zod).
According "ps axl", X86_64 version is requesting
more than 2 times VSZ memory on X86_64 than I32 (at
starting time)... (meaningful)???
The memory leak is showing up via the "free" command
where the used memory is steadily increasing over USAGE time.
Strangely enough "ps axl" is not reporting memory
usage increase (VSZ and RSS stay the roughly the
same over time for application) but an application
restart immediatly free the system memory, beside "free'
and 'ps' what is suggested to prove/show-up, memory leak
is really pertaining to application.
Could the memory leak within de decompress library
used by libclamav and beeing specific to X86_64????
My observations are very close to what is reported on
this thread....So let me know about your side of the story.
