as a followup .. here is the exception:

=======================================================

and here is a code snippet where I initialize Sigar in my object

=======================================================
    private Humidor curHumidor;
    private SigarProxyCache curProxyCache;
    private Sigar curSigar;
    
    public void activate(ComponentContext compctx) throws Exception {
        System.out.println("activating SIGAR service");
        if (logger != null) logger.info("activating SIGAR service");
        this.compctx = compctx;

        curSigar = getInstance();
        curProxyCache = new SigarProxyCache(curSigar, SigarProxyCache.EXPIRE_DEFAULT );
        curHumidor = new Humidor(curSigar);

...

    public long[] processFinderFindPidsByString( String ptqlString ) throws SigarException {
        long[] pids;
        System.out.println("entering SigarService.processFinderFindPidsByString()");
        pids = ProcessFinder.find(curHumidor.getSigar(), ptqlString);
        System.out.println("entering SigarService.processFinderFindPidsByString()");
        return pids;
    }

=======================================================

I suspect I'm doing something wrong in the initialization of these classes but have run out of ideas on what to do. Any help is appreciated.
