http://nagoya.apache.org/bugzilla/show_bug.cgi?id=10423 Premature packet header end [EMAIL PROTECTED] changed: What |Removed |Added ---------------------------------------------------------------------------- Severity|Minor |Normal Version|4.0.3 Final |4.1.12 ------- Additional Comments From [EMAIL PROTECTED] 2003-01-30 18:09 ------- I have a similar problem... Apache 1.3.26, mod_webapp (v4.1.12, connectors source bundle) on a HP-UX 11 machine, and Tomcat 4.1.12 on a separate HP-UX 11 box. I have 2 virtual servers configured. I am constantly seeing the following errors in the apache_log.YYYY-MM-DD.txt logfile from Tomcat: 2003-01-30 18:45:28 [org.apache.catalina.connector.warp.WarpConnection] Exception on socket java.io.IOException: Premature packet header end at org.apache.catalina.connector.warp.WarpConnection.recv(Unknown Source) at org.apache.catalina.connector.warp.WarpRequestHandler.handle(Unknown Source) at org.apache.catalina.connector.warp.WarpConnection.run(Unknown Source) at java.lang.Thread.run(Thread.java:536) No other logs (Apache or Tomcat) contain any further errors. Apart from these errors, the deployed servlets *appears* to be working ok. I am as yet unable to upgrade to Tomcat 4.1.18 and the latest mod_webapp so I cannot confirm yet if this error persists in these versions. I will try to do so as soon as possible. Trawling the net seemed to find other people with a similar problem but nobody had any useful suggestions or explanations. Looking up the source code where the exception is thrown...: public void recv(WarpPacket packet) throws IOException { int t=this.input.read(); int l1=this.input.read(); int l2=this.input.read(); if ((t|l1|l2)==-1) throw new IOException("Premature packet header end"); ...I see that a read() is failing when attempting to grab the headers for the incoming Warp packets. This makes me a little worried that the error is perhaps not benign and should be investigated. (e.g. is mod_webapp sending garbage in some circumstances ?) The only explanation I found offered for this error to be legitimately thrown is when a user cancels a page loading before completion, but the frequency of the errors I am seeing is way to high for that to be the case. If I can provide additional information or perform any tests to help isolate this problem please let me know - I'm not sure how to pursue a fix myself. --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
