Problem calling methods with cfengine 2.1.10

[Sven Mueller]

Hi.

I had this problem before, but it reappeared with cfengine 2.1.10 though 
I have no idea why:

We have a number of locally called methods, but for some reason, at 
least one is _never_ executed. The execution is cancelled with this message:

Trying /var/cfengine/bin/cfagent -f 
/var/cfengine/modules/InstallLeososPackage.conf -v -Z 
MD5=9eae6870f90b2f935104dd03c7d0bac3
cfengine:mx: Another cfengine seems to have done 
method-exec.InstallLeososPackage since I started


However, there is no such thing as "another cfengine". We have only one 
instance called at a time and don't call it again until it has finished.

The code which causes this is:
if (elapsedtime < 0)
   {
   snprintf(OUTPUT,CF_BUFSIZE*2,"Another cfengine seems to have done 
%s.%s since I started\n",operator, operand);
   CfLog(cfverbose,OUTPUT,"");
   return false;
   }

though I don't see a problem there.

Any idea why this might happen?

cu,
