Can you exclude some kind of crazy routing loop?
I would start with
debug ip bgp
+ events
+ updates
on a second ssh console and slowly unfasten the filter step by step.

Hi Jörg,
The line card does not reset. Under show logging during the event, the
only thing are OSPF neighbor changes when they drop and reestablish.
SSH@xmr01#sh ip bgp nei $MX_IP last-packet-with-error decode
No received packet with error logged for neighbor $MX_IP
SSH@xmr01#
On the upstream carrier BGP neighbor, when it reset, the XMR reported
the following –
Notification Sent: Hold Timer Expired
Notification Received: Cease/Connection Rejected
Thanks,
Daniel

Hi,
does the line card reset?
Also any output from
show logging
or bgp, e.g.
sh ip bgp neighbors $neighbor last-packet-with-error decode
may be helpful.

Hi everyone,
I am having a strange issue with our Brocade XMRs when I attempt to
exchange routes between a new set of Juniper MX iBGP peers and was
looking to see if anyone had any recommendations.
The Brocade XMRs have two line cards, a 20-port 1G and a 4-port 10G
card installed, and are running 5.6.0d firmware.
We are integrating two existing networks as a consolidation, with the
one network running Brocade XMR and the other running Juniper MX
routers. The issue surfaced on the XMRs when we removed route filters
on the iBGP sessions between the XMR and MX routers. When lifting the
filters and sending routes from the XMR towards the MX, everything is
functioning as normal and the MX correctly learn the routes. Our issue
becomes when we lift the filter and send routes from the MX towards
the XMR. The XMR begins to load the routes correctly, and at some
point during this process, the XMR stops forwarding traffic on the
4-port 10G line card entirely (the card to which the MX routers
interconnect), and all BGP sessions associated with that line card
flap, and OSPF adjacencies drop and re-establish.
I am using the ipv4-ipv6-2 CAM partition profile on the XMR devices.
Total number of routes attempting to be passed is a full table of
roughly 610K routes.
Even when I remove an XMR unit from service and attempt to load routes
from the MX into the XMR, the same anomaly occurs.
Any assistance would be greatly appreciated.
Thanks,
Daniel
