asterisk users - Nov 2006 - Memory leak

Has anyone noticed (using the linux command 'top') a gradual increase in
memory usage when asterisk is under heavy processing?  I am currently
pumping 4 ISDN spans (T-1) through my asterisk test system, and have seen
the memory used value in top climb steadily each second.  Concurrently, the
value for "cached" in top also climbs, but occasionally it drops, as
well.

 

Eventually, I start eating into swap and asterisk typically starts dropping
calls.  A reboot is required to recover the memory, unless someone here
knows of a less drastic method.

 

 

Thanks

Mitch,

 

I was told that 'top' can be misleading because of the fact that Linux
will generally use free space and allocate it to cache.  Try running
your tests with the 'free' command and see if there really is a memory
leak.  I think the real concern is the fact that calls start dropping
once the memory gets low enough that the system starts 'eating' into
swap and cache.  Perhaps a Linux guru out there knows if there's a way
to tailor Linux' behavior in this regard?  Also, how much RAM do you
have in the system?
