FW: [Quickfix-developers] QF 1.6 JVM crashes on connect/logon.

[Verma, S. <SV...@Cr...>]

While the apparent problem was not exactly the same as Arif's problem, I
guess the root cause was the same. Thanks for pointing me to it Asad. I
replaced start() with blockingStart() and the JVM stopped crashing.

I managed to attach gdb to the running JVM and tried debugging the C++
source code. The JVM crash is not always in the same place or at the same
execution sequence. Sometimes it crashes in ~Acceptor though I have also
seen it crash in ~SessionID. Also, sometimes it crashes as soon as the logon
message is received whereas other times it chashes after responding to the
first heartbeat message! 
 
I am using JDK 1.4.2 on RedHat Linux 8. QuickFix version, as I mentioned, is
1.6
 
It I am attaching the captured output here. Hopefully it is not too much!
Any help would be welcome. 
 
Thanks.

I am using version 1.6. I have a thread in a program that accepts
connections. As soon as the tradeclient (example) connects and sends a login
message, the JVM crashes. The output is not particularly helpful. This
happens repeatedly. No other debugging info is available. I cannot seem to
use either jdb or strace to get any further. 

1. Has anyone else run into this? 
2. How do you debug when you have problem such as this? What debugger or
what means of getting more info? 

Thanks.
