Dear Sir or Madam, we have monitored a quite strage effect in log4j logfiles, which are produced on a JBoss applicationserver of one of our customers.
I tried to google about it, but couldn´t find any hint, that somebody ever had the same problem, this is why i come to ask you about it. the effect ist as follows: the logfiles start with a line of nullvalues (0x00). this line is sometimes a large ammounts of screenpages long. It seems that there ist a nullvalue pushed to the beginning of the logfile every some time. E.g. today we had a logifle with a size of ~50MB content. anyway there were only 69 Lines of entries, and a preceeding line with 50663124 "00" - Bytes. We got the file zipped, and i would say, it has a phenomenal compressionrate: the original size is 50.674.628 Bytes and compressed it has 50.478 Bytes. That comes to a Factor of ~1000, wow ;-) Anyway, as we have no other customer, who has a similar problem, and there seems to be nobody else having such a problem, I´d be very happy for a short estimation, where I could have a look to find a cause for the effect. The OS is a SuSE10, Applicationserver is JBoss 4.2.2, and the Log4j Version is: 1.2.14 I´ll try to get the log4j.xml to check their Appenders, but maybe this description already rings a bell for you? with best regards Arend Vogtländer IT Services -- bos | bremen online services GmbH & Co.
