Re: [Condor-users] FileLock::obtain(1) failed - errno 11 (Resource temporarily unavailable)

Thanks for your consideration,


Thanks, the reason was I had called “condor start”, two times at startup.

I had wished that my mpi job can be run by fixing this error. But unfortunately it was wrong!


Best regard,

Dear All,

I have two dedicated resource ( quad-core with ubuntu 7.10 , condor 6.8.8).

Although my condor daemons are run on both of them, but I have the following error in their MasterLog file


 FileLock::obtain(1) failed - errno 11 (Resource temporarily unavailable)

 ERROR "Can't get lock on "/home/condor/log/InstanceLock"" at line 978 in file master.C


In addition my InstanceLock files are empty. Is there anyone who know what does it mean and how can I fix it.


You can only have one set of Condor daemons writing their log files to a given log directory. To ensure this, the master daemon locks the file <log>/InstanceLock. The error you're seeing means that a process already has the file locked.


In your master log, it appears you're trying to run two sets of daemons using the same log directory. Give them separate log directories (also separate execute and spool directories).


Thanks and regards,
