Re: PCMON segmentation fault

[Ralph Lange <Ralph.Lange@gmx.de>]

Hi Nicoletta,

Unless you are aiming to do something very specific, I would suppose trying the devIocStats module [1] (available in the EPICS Applications project on SourceForge [2]), which contains practically all the functionality of PCMON, but has more features, is more portable, and probably (hopefully) better maintained.

Cheers,
~Ralph

Dear all,

I have downloaded the package PCMON from http://epics.web.psi.ch/software/pcmon/, but If I try to run it I get a segmentation fault while reading the memory status.

If I run the IOC inside the debugger I do not get any error and the package works fine.

The problem apparently is in the devSysMon.c.

Reading the core file from the debugger I get:

Core was generated by `../../bin/linux-x86_64/pcMonitor st2.cmd'.
Program terminated with signal 11, Segmentation fault.
#0  meminfo () at ../devSysMon.c:437

Missing separate debuginfos, use: debuginfo-install glibc-2.12-1.132.el6.x86_64 libgcc-4.4.7-4.el6.x86_64 libstdc++-4.4.7-4.el6.x86_64 ncurses-libs-5.7-3.20090208.el6.x86_64 readline-6.0-4.el6.x86_64
(gdb)

If I cut from the database all the records related to the Memory Status which use the MEMLoad device, the package works fine.

Did anyone have the same problem? Would you know how to run the IOC outside the debugger without getting a segmentation fault?

Thank you very much.

Kind regards,
Nicoletta
