Hi Joe,

The problem is lock on EC is held by one thread let's say main thread and without EC being unlocked another thread i.e., GC thread deallocated the EC.

As Chuck is saying, the said EC is not properly unlocked.

Hi All,

    I'm not familiar with the details of ERXEC and I was wondering, when using it, if I should ever see the following exception? (Perhaps I have a buggy version - 5.0.0.8093?)

Thanks,
Joe
