Problem with methods

[Sven Mueller]

Hi.

Today we ran into a problem where a Method is not executed properly with 
cfengine 2.1.7p1

The part of the problem which is obvious is the following:

cfengine:mxfwd:InstallLeososPackage: Read arg from file 
/var/cfengine/rcfengine::/var/cfengine/modules/InstallLeososPackage.conf:Missing 
module argument package 
(/var/cfengine/rpc_in/localhost_localhost_InstallLeososPackage_MD5=6e7164f8f0d66085bfe19249c0db64e4_4

This much is displayed during a normal "cfagent" run. If I enable 
verbose/debug messages, I see (among other things of course:

root@mxfwd /var/cfengine # grep -n 0d66085bfe19249c0db64e4_4 /tmp/cf.log
14099:Create arg_file 
/var/cfengine/rpc_in/localhost_localhost_InstallLeososPackage_MD5=6e7164f8f0d66085bfe19249c0db64e4_4

14739:cfengine:mxfwd:InstallNagiosCheck: Examining child's incoming 
(localhost_localhost_InstallLeososPackage_MD5=6e7164f8f0d66085bfe19249c0db64e4_4)

14743:cfengine:mxfwd:InstallNagiosCheck: Purging expired method 
/var/cfengine/rpc_in/localhost_localhost_InstallLeososPackage_MD5=6e7164f8f0d66085bfe19249c0db64e4_4

16254:cfengine:mxfwd:InstallLeososPackage: Read arg from file 
/var/cfengine/rcfengine::/var/cfengine/modules/InstallLeososPackage.conf:Missing 
module argument package 
(/var/cfengine/rpc_in/localhost_localhost_InstallLeososPackage_MD5=6e7164f8f0d66085bfe19249c0db64e4_4)

16276:cfengine:mxfwd:InstallLeososPackage: Read arg from file 
/var/cfengine/rpc_in/localhost_localhost_InstallLeososPackage_MD5=6e7164f8f0d66085bfe19249c0db64e4_4

Why does cfagent (when called for) InstallNagiosCheck remove a file 
which isn't even intended for it? In fact, the cfagent child process for 
InstallNagiosCheck purges just the file about which the later child 
process for InstallLeososPackage complains about (it's absence).

Any hints? Is this fixed in cfengine 2.1.8? The Chnagelog entry
    Bugs in implementation of remote method protocol. Classes were
          not transferred properly.
gives a hint it might be.

Would appreciate any help.

cu,
