java.lang.IllegalStateException: Could not acquire lock


i think its a bug, but could be a limitation on the list of outgoing change sets .
i wonder how to fix the scm state. just deleting shared directory does not help.
Thanks
Serge

It is a bug, so you should submit a work item. 

For some reason the alias file (ie, the thing that records the mapping between UUIDs and aliases) is locked longer than the timeout the CLI allows. It's possible that you have another CLI running as the same user. 

Work arounds:
  1. Wait for the other process to finish.
  2. Use a different configuration directory (ie, 'scm --config /path/to/other/dir status ...')

Hi , thanks for the quick reply, i run lscm.bat from different threads so its possible that my app runs several different lscm.bat with the same user. are you saying i should not be doing it ?

i tried to use different directory. the result is the same. it still shows those blank aliases.

Then it sounds like a bug. Windows has weird locking issues, so it may boil down to that. I suggest submitting a bug.

If you're still having the problem, try hitting the 'scm' process with SendSignal (docs at http://www.latenighthacking.com/projects/2003/sendSignal/) to get a stack trace.

yes it looks like a bug, i finally could get rid of those outgoing changesets. the status command did show aliases like (----) and all the aliases it was showing as numbers were bad ones since i could not use them in commands like discard... but i turned "show uuid" on and it showed the uuids. so i was able to discard those changesets by uuid . i filed a bug for this one....
