Actually this looks like a unix system error. Error(23) is #define ENFILE 23 /* File table overflow */ [ENFILE] File table overflow Indicates either that the system file table is full, or that there are too many files currently open in the system. This error indicates that a system-wide limit has been exceeded. See [EMFILE] for the case when a per process limit has been exceeded. You need to contact your unix sysadmin to find out why this happened. (Bottom line is that it shouldn't have.:) Nathan
