[SOLVED] "Use of uninitialized value in subtraction (-) ...&quot

[yogg1]

Hi

My Zimbra Version:
zcs-6.0.3_GA_1915.UBUNTU8_64.20091118125312

I get the following warning in the "/opt/zimbra/zmstat/zmstat.out" file very often.

Use of uninitialized value in subtraction (-) at /opt/zimbra/libexec/zmstat-allprocs line 118.

With this warning the file grows ~10MB per hour!

Is there a way to avoid this warning?

Did you try searching the forums ? many many error logs in /opt/zimbra/zmstat/zmstat.out

Yea i have search for this and found the Bug report and there is only a solution for the 48h statistic Bug.

The only thing that says something to avoid the warnings was this:

By putting an if around the variable the warnings seem to be stopped.  I'm
really not sure if this is in any way correct but FYI, this is how I modified
my zmstat_allproc delta_stat function:

sub delta_stat($$$$) {
    my $prev_stats = shift;
    my $curr_stats = shift;
    my $pid  = shift;
    my $stat = shift;

    if($prev_stats->{$pid}->{$stat}) {
        $curr_stats->{$pid}->{$stat} - $prev_stats->{$pid}->{$stat};
    } else {
        0;
    }
}

The author says he has no idea if this is correct. Maybe this self made patch is in some way or in some environments harmful and i get other problems. There are also no comments about it if this is a good or bad solution.

The only thing that i can say is that i have no idea about the Zimbra code and i don't would test such patches (where the author is not sure about it) on working environments.

Can someone say something about this patch?

I have also found out that this problem only comes up in 64 bit environments. I have some 32 bit Zimbra servers with the same version where i don't get this warnings.
By the side the "sub delta_stat($$$$)" functions in "/opt/zimbra/libexec/zmstat-allprocs" are on 64 and 32 bit identically (line 111 - 119).
It seems for me that the above posted patch only avoid the warning and does not solve the problem itself.
How can it be that "$prev_stats->{$pid}->{$stat}" is uninitialized?

And sorry i have to say that but i think the only one who should mark my posts as solved was me

Edit:
Is there a way to fix the tile of the post?

Nope; I am marking as solved as a bug has been filed and the officially supported fix will be shown there when the Zimbra team resolve it.
