-------------------------------------
In IdUserGroup.java:
{noformat}
synchronized private boolean isExpired() {
return lastUpdateTime - System.currentTimeMillis() > timeout;
}
{noformat}
should be :
{noformat}
synchronized private boolean isExpired() {
return System.currentTimeMillis() - lastUpdateTime > timeout;
}
{noformat}
> NFS failed to refresh the user group id mapping table
