Have you actually been able to read /etc/passwd this way? I tested this on a few of our servers and it does not work. As far as I know, there is access

 26 Jul 2013, Konstantin Olchanski, Bug Report, abort on buffer overflow in odb.c::merge_records()

I would be in favor of not curing the symptoms, but fixing the cause of the problem. I guess you put the watchdog disable into mhist, right? Usually mhist
is called locally, so no mserver should be

familiar situation, "too much data", you dice t or slice it, still too much. BTW, you can try to generate history
plot ODB entries from your program instead of from the history plot editor. K.O. |
