[c-nsp] Freeing up BGP memory?

[Randy]

Hello all,

With three full tables on a SUP720-3BXL (SXI5), memory is getting 
tight.   I removed soft reconfiguration inbound on all peers (and 
cleared them all), however memory usage is not changed (still about 75% 
utilized).  Does IOS hold onto once-used BGP memory or am I not 
understanding the effect of removing soft reconfiguration?

Thanks,
