After installing 10.3 you may see this message in the VNM.OUT:
Nov 16 11:40:50 ERROR TRACE at VNM.cc(493): SpectroSERVER unable to set core unlimited. The system level error was: Operation not permitted
We changed the code to change the ulimit corefilesize to unlimited so that the linux OS could create a core file if the SpectroSERVER were to crash.
This will be fixed in the next release of Spectrum.
The temporary workaround is to manually set the ulimit corefilesize to unlimited:
As root user run:
This will show you the ulimit values.
ulimit -c unlimited
This will set the corefilesize to unlimited.
