Cadence
...
won't

start,

doesn't

exit

cleanly,

or

complains

about

files
...
- Ensure
...
- you
...
- are
...
- not
...
- running
...
- Cadence
...
- anywhere
...
- (i.e.
...
- research
...
- server,
...
- linuxpool,
...
- amdpool,
...
- etc.)
...
- To
...
- find
...
- your
...
- cadence
...
- processes
...
- run
...
- the
...
- command
...
No Format
...
ps -elf | grep cadence | grep <login id>
...
For
...
- example:
...
No Format
...
ps \-elf \| grep cadence \| grep yyy33
...
You can omit the "| grep cadence" just to see all your processes.- You can kill all your processes, including your login shell, by typing
No Format kill \-9 \-1
...
- Check your processes again per step 2 until you are sure your cadence processes are gone.
- You may need to clean up Cadence lock files. You can run the command:
No Format find . \-name .snapshot \-prune \-o \-name}} {{{*}cdslck{*}}} {{
...
-exec rm {} \;
...
When starting Cadence,
...
an
...
error
...
indicates
...
that
...
cds.lib
...
can
...
not
...
be
...
read.
...
In
...
some
...
instances,
...
it
...
indicates
...
there
...
might
...
be
...
a
...
problem
...
with
...
cdsd
...
daemon.
...
Various
...
security
...
updates
...
affect
...
NFS
...
periodically.
...
You
...
need
...
to
...
set
...
the
...
environment
...
variable
...
DD_DONT_DO_OS_LOCKS
...
before
...
starting
...
cadence.
