Hi,

I've havent come across this problem myself. I looks quite interesting. How
often does this happen ? Do you still have the hs_err_pid*.log files for the
crashes that have happened. If so it might be worth looking back through
these.

If the crash is consistant in terms of where and how it occurs I would tend
to suspect a JVM bug. If the crashses are more random then I might begin to
suspect the hardware.

Your using the Hotspot Server VM - it would be intersting to see if you can
re-produce this bug with the hotspot client VM - as if it is not possible it
may indicate a bug in the Hotspot Server VM's compiler or somthing along
those lines.

Really we should not be able to crash the virtual machine from just java
code which is why I suspect a JVM problem or hardware problem rather then a
problem with jaybird itself.

I hope this is of some help.

Ryan

Subject: [Firebird-Java] JVM crashes from exception in JDBC driver


Hi All

I'm getting this problem quite often in a production system.
The JVM crashes with and error and it's usually fro mthis
FBBlob$FBBlobOutputStream class...
Any solutions? I think I'm running a fairly recent (about 1 or 2 weeks old)
CVS version of the driver.

Regards
Kenneth
