Hallo und Halli,
es ist schon drollig, ich habe da doch ein Programm unter Java 5 gebaut was Dateien für die Weiterverarbeitung in einigermaßen paralleler Art und weise rumrangiert und dabei in der Lage ist andere Anwendung anzustoßen.
nun bekomme ich ganz urplötzlich eine Meldung auf der Solaris-Console, mit der ich nicht so ganz umzugehen weiß, da es offenbar hier nicht um eine Exception handelt.
Ich habe keine Ahnung was diese Meldung ausgelöst hat, noch ob ich dies als Problem werten muß. Es war recht sporadisch und eigetnlich zum erstenmal dass ich sowas sehe.
Sie kam nach einiger Zeit als das Programm eigetnlich nichts zu tun hatte.
hier die Meldung (es ist offenbar die liste der Threads)
Habt ihr sowas schon mal erlebt, und was hat das genaues zu bedeuten?
Für Eure Meinung und Erfahrungsaustausch echt dankbar
