REPORT #725 Details.
Project: Tomcat
Category: Bug Report
SubCategory: New Bug Report
Class: swbug
State: received
Priority: low
Severity: critical
Confidence: public
Environment:
Release: 3.2.1
JVM Release: jre1.3.0 (linux)
Operating System: Linux Debian
OS Release: 2.2
Platform: PC (i386)
Synopsis:
segmentation violation at first http request
Description:
I have observed the following strange behaviour with both Tomcat 3.1 and 3.2.1.
We have several machines on our network all running Debian Linux. On some of
them, tomcat works fine. On others it crashes after the first http request. The
error it produces in such cases is listed at the end of this email. The
machines where it works are all machines which have public IP addresses whereas
those where it doesn't are not visible to the internet as a whole. I don't see
why that should matter but it might help figure out what the problem is.
Another difference I have noted is that the starting of the Tcp seems to take a
very long time in the cases where it fails compared to the time taken on the
machines where it works.
Any idea if this is a bug?
