Blocked log file / logging
Dear list,
I'm having a problem recently with my application which uses log4j.
The application does several loggings within Swing's Event Dispatching Thread -- like a simple
log.warn("my message");
And sometimes this leads to a blocking of the application for about 10 to 15 minutes.
When I debug the application and pause it, the EDT is the only thread trying to write to a file.
The stacktrace of it looks like:
FileOutputStream.write(Byte[]) (code line unknown here)
... (several other calls between the call of Logger.warn() and FileOutputStream.write())
Logger.warn()
And at this point it hangs for the said 10 to 15 minutes. Then it continues.
I have no idea yet what caused this, since it's just existing since about 2 or 3 weeks.
Any idea of how to diagnose what's the problem here?
Is there anyking of this issue known to log4j?
The used version of log4j is 1.2.16. Unfortunately, I cannot just change it to something newer.
Kind regards, Michael

Posted by Köther,

Thanks for your hint, Brett.
At the bottom of my message I have pasted a complete stack trace where the logger was blocked.
Again, it takes about 10 to 15 minutes usually, and then the application continues to work.
>From what I read in the bug reports, the issue seemed to appear on Solaris.
My machine runs with Windows 7 x64. The used JVM is 1.6.0_20-b02. Again, Log4J is 1.2.16.
Does the stack trace help?
I myself cannot say I'm sure it's Log4j, but do not really know how to diagnose this.
Best, Michael
