Hello JonRussell,

Can you please check if you have the dependency perl-Thread-Semaphore installed on your system?

You can run the following find command in the terminal:

find / -name Semaphore.pm

If there is no result, this may be the cause of the errors.

You can try and install the package perl-threads-shared

Please let us know if this solves your issue.

Kind regards,

Sergio B.

Thanks for the fast reply.

I do have Semaphore.pm

# find / -name Semaphore.pm
/usr/lib64/perl5/IPC/Semaphore.pm
/usr/share/perl5/Thread/Semaphore.pm

Hello,

Can you run the following cpan command in your terminal?

cpan -i Thread::Semaphore

This will install some necessary files left out in the yum installation.

After this the problem should be resolved.

Let us know how it went.

Kind regards,

Sergio B.

I had the same issue after updating to 768 using Warp Update Online.

The fix also worked for me, but I had to first install perl-CPAN (CentOS 7).

yum install perl-CPAN

BTW, Pandora was running for several hours in this error state before I applied the fix. The /var/log/pandora/pandora_server.error file grew to over 8GB in that time.

Pandora was just writing the following line as fast as it could over and over:

Can’t locate object method “down_timed” via package “Thread::Semaphore” at /usr/lib/perl5/PandoraFMS/ProducerConsumerServer.pm line 237.

Hello,

The log grew over the time because it was trying to perform the tasks in hand used by the Semaphore.pm dependency and by not having it installed was giving notice about the error.

You can simply remove most of those log lines in order to reduce the log size easily with vim.

Also it’s always recommended to use logrotate to rotate any log that might potentally grow in size in order to avoid to fill up the disks.

Kind regards,

Sergio B.
