If it were a file permissions issue, I would suspect it would be an all or nothing situation, would you not? As I mentioned, the strange thing is that once you stop and restart the service everything is fine, and it appears to be triggered by sometimes reloading the config file. I have gone on and explicitly added the postgresql service account and given it full access rights to the directory. Maybe this will keep it from recurring. -----Original Message----- From: Tom Lane [mailto:tgl@xxxxxxxxxxxxx] Sent: Thursday, May 25, 2006 1:59 PM To: Benjamin Krajmalnik Cc: Scott Marlowe; pgsql-admin@xxxxxxxxxxxxxx Subject: Re: [ADMIN] Strange errors in log file "Benjamin Krajmalnik" <kraj@xxxxxxxxxxx> writes: > Restarting the service resolves the problem, so it is not a file > permissions issue. It sure *looks* like a file permissions issue. FWIW, I see that port/win32/error.c translates these Windows error codes to EACCES: ERROR_ACCESS_DENIED ERROR_CURRENT_DIRECTORY ERROR_LOCK_VIOLATION ERROR_SHARING_VIOLATION ERROR_NETWORK_ACCESS_DENIED ERROR_CANNOT_MAKE ERROR_FAIL_I24 ERROR_DRIVE_LOCKED ERROR_SEEK_ON_DEVICE ERROR_NOT_LOCKED ERROR_LOCK_FAILED It would appear that the underlying problem is one of these. regards, tom lane
