Hi all.

Is there any process or graceful way (except reload) to free allocated 
memory by BGP process
after shutting down some of BGPs sessions from route reflectors?  (SROS 
6.1R9)

One of my SR-1 reached  memory alert:

A:SZCZC001RT03# show system memory-pools

===============================================================================

Then I shut down the two bgp sessions from a total of 3 full RR feeds, but 
BGP process didnt freed any
memory (in contrast the other SR-1 routers that have only single feed have 
only ca. 60M used for same bgp table).
I expect that some kind of garbage collection should start but no effect 
observed.

So I feel some trouble behind corner...  On SR-1 the same hardware (looks 
like IOM-20g) is co-used by
IOM  and CPM functions (IOM process eating constantly 360M)  but 1GB of 
memory is definitely not enough.
Is there any way (i mean even unsupportted but working) to upgrade the mem 
on SR-1?
