[Xymon] reopen_file: Cannot open new file: Permission denied

(Top posting due to encoding strangeness)

Hi Ian,

Unfortunately, the routine which calls this is used in a number of different locations so it might be hard to track down w/o more detail. Approximately what interval does the message occur on when you leave the session open?

The bulk of the calls to this IIRC are dealing with log file output, and usually involve reopening both stdout and stderr, so it's most likely log related. Even in 4.3.17, xymonlaunch should be redirecting the stderr output to a designated LOGFILE entry in tasks.cfg and/or clientlaunch.cfg; I'd check either of those for any non-disabled tasks that don't have a LOGFILE entry and add one in. That should either a) solve the problem, or b) redirect the re-open error into an appropriate destination, since the initial reopen is done by xymonlaunch prior to forking.

HTH,

"reopen_file: Cannot open new file: Permission denied" I can;t work out what file it is trying to re-open and why therefore find out why its permissions are wrong. I've had a shufti at the ..../server  folder and nothing is leaping out as the "wrong" ownership ...  what I do see is then ...../server/www/snap,  ....server/wwww/rep have a group ownership of apache and everything below it is apache:apache but that is presumably tied up with the apache web server that presents xymon to the world so not likely to be it presumably.

the only other place I thouht of was /var/logs/xymon but the user can create a new file OK in there.

Anyone any pointers to where to start looking?  or to start investigating further?
