Two common causes of crashes, in my experience, are using the
JDBC-ODBC bridge (its not thread safe and when concurrent access occurs it
crashes the JVM). The other is in the JIT complilation. I've had a lot
less trouble with the newer JDKs (1.2.2_007) than the older ones (1.2.2_002
and 004).
The solution to the second problem is pretty obvious - upgrade your
JVM or turn off JIT. The first solution you can either serialize requests
or find new database drivers.
If your problem isn't one of these two things, I would suggest
looking where you are using native code as well as the differences between
the two machines (including usage, it the one with the higher load crashes
more frequently then the problem is probably something you are using isn't
thread safe)

Subject: Tomcat Crashes
hi,
I have Tomcat 3.1 and jdk 1.2.2 on TWO Windows NT machines.
Both the machines are loaded with the same code,same database.
But on one machine it is causing Dr.Watson error 2-3 times a day whereas
the other one is working properly.
Could you help in anyway on this?
thanks in advance
kishor
