ERROR Failed to flush writer, java.io.InterruptedIOException

[laredotornado]

Hi,

I'm running Java 1.5 on Weblogic 9.2.2 (Solaris 9). During the
execution of my program, I'm getting this error ...

It is happening on this line:

log.debug(this.cpSwitchAttributes.getCLLI() + " exiting id=" +
createTime);

Per a suggestion I read online, I checked to see if I have enough disk
space, and it appears I do ...


orma3% df /
/ (/dev/vx/dsk/bootdg/rootvol): 1587550 blocks
253027 files


Any other ideas on how to troubleshoot this problem? Thanks, - Dave

You might check permissions along the path to the log file. Also, `df /`
describes free space on the root file system. You should probably check
the filesystem that contains the log file, perhaps using `du`.

In addition to John's excellent suggestions have you checked the size
of the log file itself? Is there a maximum file size that cannot be
exceeded that your logfile has hit? Log files do tend to grow bigger
over time.

Good point; thank you for expanding on this. I have come to rely on
logrotate under Linux, and I see that Solaris 9 has a convenient new
administrative feature, lagadm:
