64bit, convertd, verity causing java thread to crash

[jnetman1]

Our convertd thread crashes regularly using the network edition trial on 64bit RHEL. The perl scrip starts it back up again, but it's keeps dying. Eventually, most of the messages are getting through, but it can take a long time. I'm guessing that it has something to do with native calls to 32bit verity libs. Are there 64bit versions of these libs available? Java crash log sample below:

64bit is not supported, and you've found at least one of the reasons why

You best bet is to install 32bit RedHat and things will be much happier.

Thanks for the info. That seems to be the only thing that doesn't work, so it's something of a bummer. I confess it took quite a bit of perl wrangling to get the rest working, but all else does work correctly on 64bit.

No doubt somethings can be made to work but some just won't. I think the biggest thing you lose (other than some hair trying to hack this yourself) is the assurance of our QA suite running over it for a few hours to ensure all the interworkings are in order.
