    Every five minutes cfdcollect logs this to syslog:

    Dec 17 19:22:36 pecan cfdcollect[7233]: [ID 183499 local6.info] [I]
    awakened by alarm.

    sleeping for 293 seconds.

    Then cflowd dumps core. cflowd continues to show up in a ps listing
    though.

    This is on a Netra T1 running Solaris8.  It has 512mb RAM and 18G of
disk on /cflow

    Any ideas what's going wrong?
