cacti boost error

[telaorui]

Hi,

These days my cacti appear the problem of graphs. Sometimes appear the traffic and sometimes not.

I checked other hosts. They are no problem. just one host appear this problem.

I check the 'syslogs' that has error as below:
Cacti[547]: CMDPHP: ERROR: Can not start MAC Trackinging process. There is already one in progress
Cacti[22218]: BOOST: ERROR: Timeout detected. Boost server is down. Contact support immediately!!
Cacti[30005]: BOOST: WARNING: RRD Update Warning 'FAILED' for Local Data ID '55'


Please help me. Thanks.
