hello:

I find some problem under AIX6.1 system.  

the log:

2017-03-21 14:02:41 WARNING additional group memberships couldn't be set because getgrouplist()and setgroups() are not available on this platform
2017-03-21 14:02:41 INFO nxlog-ce-2.8.1248 started

and i sccan the source code, find:

static void nxlog_set_groups(nxlog_t *nxlog, apr_uid_t uid)
{
    gid_t grplist[100];
    int ngroups = sizeof(grplist);
    char *user;
    apr_status_t rv;

    if ( (rv = apr_uid_name_get(&user, uid, nxlog->pool)) != APR_SUCCESS )
    {
    log_aprerror(rv, "couldn't resolve uid %d to name", uid);
    return;
    }
#ifdef HAVE_GETGROUPLIST 
# ifdef HAVE_SETGROUPS

    if ( getgrouplist(user, getgid(), grplist, &ngroups) == -1 )
    {
    log_error("couldn't get group membership for user %s (uid: %d), too many groups?", user, uid);
    return;
    }
    if ( setgroups((size_t) ngroups, grplist) != 0 )
    {
    log_errno("couldn't get group membership for user %s (uid: %d), setgroups() failed",
          user, uid);
    return;
    }
# else
    log_warn("additional group memberships couldn't be set because getgrouplist()"
         "and setgroups() are not available on this platform");
# endif
#else
    log_warn("additional group memberships couldn't be set because getgrouplist()"
         "and setgroups() are not available on this platform");

#endif

}

I don't what' wrong with this problem, thanks.
