Error messages and high cpu usage while scanning

[bxkx]

Hello, can anybody help me? Every time I apt-get upgrade and needrestart starts scanning it also shows me the following:

# Use of runtime loader module Module::Implementation detected.  Results of static scanning may be incomplete.
# Use of runtime loader module Module::Runtime detected.  Results of static scanning may be incomplete.

The CPU usage is kind of spiking when that happens. I'm on Debian 8.

I get the same messages when it tries to detect updates in the Thruk package in Debian 8. This breaks the nagios plugin mode.

Could you please provide the output of needrestart -v when the problem does occur? We need to figure out the conditions triggering those messages and the increased CPU load.

Here are the logs for -v and -p: out.txt

oh by the way: I am using 2.9-1~bpo8+1 (jessie-backports).
In 2.8.1 the CPU-usage was much higher and it needed about 10 seconds after displaying the "# Use of runtime..." messages.
This has vanished in 2.9.1 - only the messages remain, which are bad in the Nagios-plugin output.

Thanks for the logs!

• Warnings: This is triggered by Module::ScanDeps for dynamic loaded modules. The warning messages seems to be hard coded - I need to check how to supress them...
• CPU usage: There was a caching layer added in 2.9 (Debian Bug#826247) to stop parsing interpreter source files twice which improves the scan time if you have many interpreter instances running.
