perfSONAR User Q&A and Other Discussion

[Andrew Lake <>]

Hi,

You might want to run memtest or a similar tool to make sure your system memory is ok. It might also be worth trying a reboot. The fact it hit multiple services and that the segfault is happening on a pretty harmless looking echo in the start-up script (not even in the MA code) makes me wonder if something else is happening.

Thanks,

Andy

Hi,

I’m working on perfSONAR v3.3.2 for several months, and all modules works well when suddenly all Measurement Archive(perfSONAR-BUOY, PingER, SNMP) breakdown this morning. The status on Web Interface says ’Not Running’.

I’ve tried to start it manually but I get segmentation fault: 

service /etc/init.d/perfsonarbuoy_ma restart

Any insights appreciated.
