Hi
I have 6.12 x64 (VM)
1G of memory
4 CPU
3 BGP Peers - full tables with filtering (5K, 12K, 14K prefixes)
My free ram has been slowly increasing (same on both of my BGP peers), my other VM’s are fairly stable.
Zabbix has flagged a warning as there is only 20% of free memory left
Is this normal, was there a memory leak on 6.12
I’m also running OSPF on this box as well
/ip route print count-only
188433
seems like this started about 1 month ago. previously it was stable around 50%.
I don’t have a date time changelog so I am not sure what changes happened around then 
So I be concerned, I am planning a reboot, patch to 6.15 in 2 weeks.
