After troubleshooting it some more, I determined that the problem occurred due
to a corrupted cfservd ChecksumDatabase. The backtrace from the 2.1.14 version
was:
#0 0x40045d95 in __bam_split () from
/usr/local/cfengine-test/BerkeleyDB.4.3.27/lib/libdb-4.3.so

#9 0x400edc6f in pthread_start_thread (arg=0x44204be0) at manager.c:279
Removing the checksumdatabase file resolved the problem. Is there any way to
modify CFE to be insulated from dbm corruption?
Thank you,

Hello, I am experiencing frequent cfservd coredumps (about every 30 minutes)
with 2.1.14 and 2.1.17. This on RHEL ES2.1. I've pasted the backtrace and
logfile messages below.
Any suggestions on solving the problem?

The debug output cuts off, I suspect that unflushed buffers are the problem. It
would be nice if the debug output performed a fflush() after each print to
avoid losing data.
