The first part of the stack is: J java.lang.Throwable.fillInStackTrace()Ljava/lang/Throwable; J java.lang.IllegalArgumentException.<init>(Ljava/lang/String;)V J java.lang.Integer.parseInt(Ljava/lang/String;I)I which means that the fillInStackTrace() method is the actual cause of the crash. This is a native method (at least in the Sun JVMs I've checked), so can easily cause the crash. Looking further up the stack, it seems the parseInt() is being used by getInputStream() while reading an HTTPSample response. I guess the input stream needs to be partially read before passing it back to the caller in order to strip off the HTTP headers. The most likely number it needs to parse is the Status Code (e.g. 200). If you are interested, you could always use a protocol analyser to see if the HTTP headers are well-formed or not. There must be some unusual combination of circumstances which causes the fillInStackTrace() method to fail. This method will be called lots of times, and the JVM would hardly work at all if it always failed, likewise if invalid integers always caused a crash this would surely have been noticed before the JVM code was released. Minor changes to the test plan may allow you to proceed with testing, but the only long-term solution is to install a JVM without the bug... > Thanks, > Andrew > > > Current thread (0x0000000101b8c000): JavaThread "Thread Group 1-2" > [_thread_in_vm, id=768688128, stack(0x000000012dc14000,0x000000012dd14000)] > Stack: [0x000000012dc14000,0x000000012dd14000] > Java frames: (J=compiled Java code, j=interpreted, Vv=VM code) > J java.lang.Throwable.fillInStackTrace()Ljava/lang/Throwable; > J java.lang.IllegalArgumentException.<init>(Ljava/lang/String;)V > J java.lang.Integer.parseInt(Ljava/lang/String;I)I > J sun.net.www.protocol.http.HttpURLConnection.getInputStream() > Ljava/io/InputStream; > J org.apache.jmeter.protocol.http.sampler.HTTPSampler.readResponse > > (Ljava/net/HttpURLConnection;Lorg/apache/jmeter/samplers/SampleResult;)[B > > J org.apache.jmeter.protocol.http.sampler.HTTPSampler.sample > > (Ljava/net/URL;Ljava/lang/String;ZI) > > Lorg/apache/jmeter/protocol/http/sampler/HTTPSampleResult; > J org.apache.jmeter.protocol.http.sampler.HTTPSamplerBase.sample > > (Lorg/apache/jmeter/samplers/Entry;) > > Lorg/apache/jmeter/samplers/SampleResult; > J org.apache.jmeter.threads.JMeterThread.run()V > j java.lang.Thread.run()V+11 > v ~BufferBlob::StubRoutines (1) > > > > > On 11/12/08 8:24 AM, "sebb" <[EMAIL PROTECTED]> wrote: > > > > On 12/11/2008, Andrew Ralph Feller, afelle1 <[EMAIL PROTECTED]> wrote: > >> Has anyone encountered Jmeter crashing in the middle of a test?
