In the absence of any fatal errors (that are indicated in this
section), a BGP peer MAY choose, at any given time, to close its BGP
connection by sending the NOTIFICATION message with the Error Code
Cease. However, the Cease NOTIFICATION message MUST NOT be used when
a fatal error indicated by this section does exist.
A BGP speaker MAY support the ability to impose a locally-configured,
upper bound on the number of address prefixes the speaker is willing
to accept from a neighbor. When the upper bound is reached, the
speaker, under control of local configuration, either (a) discards
new address prefixes from the neighbor (while maintaining the BGP
connection with the neighbor), or (b) terminates the BGP connection
with the neighbor. If the BGP speaker decides to terminate its BGP
connection with a neighbor because the number of address prefixes
received from the neighbor exceeds the locally-configured, upper
bound, then the speaker MUST send the neighbor a NOTIFICATION message
with the Error Code Cease. The speaker MAY also log this locally

Check the syslog for messages mentioning BGP. Usually where 'Cease' is mentioned there will be a little more details explaining why that error was encountered.
