cfagent hangs

[Jeff Wasilko]

Hi:

I've been having problems with cfagent hanging for multiple days.
It's usually started by some sort of network problem (we've had a
bit of instability here that we've traced down to a failing gigE
switch).

cfagent is started by cfexecd. Is there any way to get cfexec to
kill the wedged cfagent?

lexx 7 ># ps -ef | grep cfagent
    root 17435   375  0   Nov 22 ?     0:04 /is/local/state/cfengine/bin/cfagent

lexx 8 ># truss -p 17435
recv(8, 0xFFBF2618, 8, 0)       (sleeping...)

It seems to be hung in a copy of a big tree (pushing out our
/usr/local equivilent):

This is the mail I got from cfengine when I killed the hung
cfagent:

cfengine:lexx: Received signal 15 (SIGTERM) while doing
[lock.cfagent_conf.lexx.copy._is_dist_pkg__is_dist_pkg]
cfengine:lexx: Logical start time Sat Nov 22 16:20:34 2003
