Ever since I upgraded our server running Groupwise (v7.02), from Netware
6.5 sp6 to Netware 6.5 sp7 we have been getting quite a few of the
"Deadlock detected waiting for spinlock currently owned by CPU" related
abends. After this abend happens the server usually halts. This has
happened about 10 times in the last month at varying intervals. All
abends look very similar to each other, here are summaries of the last
few:
