Short: Driver runs out of filehandles
Date: Fri, 30 Jun 2000 14:49:36 +0200
From: Freaky <Freaky@UNItopia.RUS.Uni-Stuttgart.DE>
Type: Bug
State: Done - fixed in 3.2.8-dev.214

Analysis: forgot to delete the old ixopen() statement in object.c when
making the change in 3.2.8-dev.210, thus opening every savefile twice.
Hi,

Ich habe endlich wieder ein paar Cores. (vom dev-211)
Jetzt laeuft in UNItopia wieder der dev-200.

Die Abstuerze kamen jeweils alle zwei Stunden.

(the crashes themselves were produces by a bug in the error handling
of write_file)

Es sieht so aus, als ob der dev-211 keine Filehandles mehr bekommt ab
irgendeinem Zeitpunkt.
Es kommt auch die Fehlermeldung einige Zeit vor dem Absturz;

2000.06.30 08:09:58 Could not open save/VAMPYR_LISTE.o.tmp for a save.
(/save/* darf wirklich jeder schreiben und die Permissions sind korrekt)

2000.06.30 10:57:00 Could not open var/players/x/xih.o.tmp for a save.

In jedem Debuglog steht das dann drin bei dev-211

Liegt das evtl. daran, dass UNItopia den Access-Check ausgebaut hat?
Werden dadurch Filehandles nicht mehr freigegeben?

(shouldn't be the reason)
