-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA512 Hi, Petr,
An update using flock to ensure only one thread is writing an index file has been implemented in SVN Revision 747. Please give it a try if you are on a system that using posix file system. As for cleaning up the corrupt index files, you should be able to using the command line tool 'ibis' to rebuild the indexes with an additional flag of '-z' to zap away all existing index files. Good luck. John On 8/25/14 11:02 PM, Petr Velan wrote: > Hello John, > > We've encountered an issue when using multiple instances of data > access tool over the same data.
