Hello,
I've been running IBM's 1.1.8 on Red Hat 6.2 machines in a three-server
load-balanced configuration, as the VM for JServ 1.1.2 and GNUJSP
1.0. Every couple of days, I get the error I've appended below, which
causes the VM to shut down - JServ gets it back up all right, but we lose
session information and some angry customers in the process... This
happens on all the three load-balanced nodes. All three are identically
configured.
I wonder, has anyone had the same sort of trouble before ? I hunted around
on the IBM web site and couldn't find anything, so I thought perhaps
someone out there would have an idea.
As an aside, are there any recommendations for the ideal VM to use on a
system such as the one we're running? We use only server-side 1.1.x code
so a recommendation would be very helpful indeed. Would Blackdown's 1.1.8
do the job better ?
Many thanks,
Hari.
The trace is appended below. I apologise for its length, but here it is in
all its unedited glory:
