An issue was reported receiving error #767 (FALG_ERR) which indicates “fixed length record offset not aligned”. The error indicates a read request at an unexpected data file offset. The error was returned from GTEREC(). After reindexing the problem cleared.
To diagnose an underlying cause, this diagnostic option was added. When present in ctsrvr.cfg, a stack trace will be generated when a FALG_ERR is encountered. There is no anticipated overhead with this tracking enabled, until an issue occurs. And then, the overhead is the time to generate the stack trace file.
