hello,
our customer has a strange problem, that I don't know how to answer.
There is a router, that has 7 contexts including local.
2 full BGP routers in different contexts, 4 full feeds (1 in one
context, 3 in other).
So - 2x full FIB.

There is only 12MB of memory left... ok - 1G in such case is a little.
#show memory
Memory: Total 802732k, Used 754080k, Free 12192k, Reserved 24k
There is anoter SE100 - with only 2 contexts - local and other for BGP.
Also 4 BGP feeds, but just one full FIB. Much more of VLANs (60 vs. 6)
lot of QoS etc.

System Bootstrap version is PowerPC,rev2.0.1.4
Installed minikernel version is 2.7
There is 140MB of memory left.
Ok, I understand that 2x full Feed is heavy, but look:
*ntp 3333 2 31716K 00:00:00.44 0.00% run
00:19:47
ntp 488 1 4264K 04:20:35.25 0.00% run
99w6d
*arp 265 1 31500K 00:07:46.40 0.00% run
4w1d
arp 459 1 4572K 24:55:58.44 0.00% run
99w6d
Similar with qos and dot1q. * - is the router with 12MB of free memory.
Is this normal ?
Is it some function that more contexts reserves more memory for each
process like arp/ntp
so that it occupies much more memory than just with a few contexts ??
Regards,
Marcin
