Hi All,
Can anyone think of any quick pointers as to why some code originally
written under 6.4 amd64 - when re-compiled under 9.0-stable amd64 takes up
a *lot* more memory when running?
The code involved is a sendmail Milter, and a TCP server type program (that
runs up a large number of threads [~700] at startup).
Both were previously compiled with:
-O2 -pthread -lc_r
They're now compiled under 9.0-S with just:
-O2 -pthread
As an example, under 6.4 the size/res for one reported by top is 81Mb/48Mb
- and for the other is 44Mb/9Mb [this is after it's been running for weeks].
Under 9.0-stable the initial memory used by the processes just after
starting rises to 625Mb/128Mb and 519Mb/65Mb respectively.
Is that something I need to worry about?
They've not been running longing enough yet to see if anything is 'leaking'
(i.e. if size/res continues to go up). Just thought I'd ask if there's a
simple/possible explanation for this - and if it's something I need to
worry about...
Thanks,
-Karl
