Summary: Chainsaw receives string index out of range error when
using sockethubreceiver
Product: Log4j
Version: 1.3alpha
Platform: PC
OS/Version: Windows XP
Status: NEW
Severity: normal
Priority: P3
Component: chainsaw
AssignedTo: log4j-dev@logging.apache.org
ReportedBy: earl507@yahoo.com
I am receiving a runtime error when using chainsaw.. This occurs when I am using
a SocketHubReceiver/Appender. The runtime error comes from the core of log4j and
not chainsaw, but I only see it in chainsaw. Essentially, the
org.apache.log4j.PatternLayout object contains a StringBuffer that is getting
overwritten by simultaneous calls to PatternLayout.format() during high activity
periods. I was able to resolve this locally (I can't check in code due to my
company's firewall) by adding a 'synchronized' keyword to the
org.apache.log4j.PatternLayout.format() method.
After the error occurs, it renders chainsaw unusable.
Thanks,
Eric
