Hi Nicoletta,
We are using this package all the time without problems. But I cannot
say at the moment if the version we are using is exactly the same as the
one on the download site. Maybe that one is old and not suitable for 64
bit. I have to check that. Also the developer of that software is not at
PSI any more.
To run outside a debugger, do this before running the ioc:
ulimit -c unlimited
The run the ioc, let it crash and do a post-mortem analysis with the
debugger and the core file created by the crash.

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.

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
