coredump using tomcat 3.2.4

hi, All,

We recently experienced a coredump when using an
embedded tomcat servlet engine (version 3.2.4). The
last hint was two stack traces showing socket read
timeouts. The java version we were using is 1.2.2_12
on solaris 2.8. Has anyone seen something similar?

I am not trying to solve the problem here but any
ideas on how to trace the cause of the coredump is
greatly appreciated. 

Thanks a lot,

John

PS: the stack trace looks like:

java.io.InterruptedIOException: Read timed out

Posted by shawn <sh...@wnsi.net>.
#] gdb /path/to/executable /path/to/corefile

<...loads all the symbols from the core ...>

(gdb)bt

<.. prints the stack trace of the segfault ..>

I have not done this with tomcat.  your milage may vary.


If you do not have a core you can do it this way....

#]gdb /path/to/executable
(gdb) run -X

( cause your app to crash )

(gdb)bt
