Created attachment 204696 [details] Add a check in witness to allow taking a lock recursively When using a recursive lock, witness trigger an errors if the lock is taken twice although it is an expected case. This was observed when using a rm_lock created with the RM_RECURSE flag. So I add a check in witness to check is the class of the lock have the LC_RECURSABLE flag set before triggering the error. Note that this is a quick fix which could probably be enhanced.
