segfault in SSLeay.so

[scratttt]

Hello,

When I run the Perl plugin it returns the following error:
kernel: collectd [10813]: segfault at c58 ip 00007f6e3d89f359 sp 00007f6e36492620 error 4 in SSLeay.so [7f6e3d892000 + 6f000]

Our collectd configuration:

LoadPlugin perl

<Plugin perl>
IncludeDir "/apps/collectd/scripts/NetApp"
BaseName "Collectd::Plugins"
LoadPlugin NetApp
</Plugin>

The version of collectd is 5.5.0.
The OS version is CentOS Linux release 7.3

Before we had this plugin and it worked correctly (the version of collectd and OS is the same).

Thanks!!
Regards.

Hey, do you get this error after the FlashCache Module? Or did you have it before? Best regards, Alex

Hi,

It must be a problem in the library file, I have managed to go one step further.

I have also noticed that if in the file "netapp.ini" you don't have the option "ExcludeModules" configured (even if it is equal to "no"), the threads never start.
my $exclude = $Config{ $hostname . '.ExcludeModules'};
if($exclude){

It is necessary to put the option "ExcludeModules" in the configuration file:
[filer1.example.com]
Username=USERNAME
Password=PASSWORD
Mode=cDOT
Modules=CPU,Aggr,Volume,NIC,Disk
ExcludeModules=no

Now I see that it executes the threads, but it gives a "memory leak" error of the process:

Does the netapp connection work? Maybe try with one of my nagios scripts in github ...

Yes, the connection works.
