SPARC problem with WAL additions?

Hi All,

I'm seeing a funny with the new WAL aware postmaster.

After doing a "kill" on the postmaster process I get another
postmaster process which appears to be spinning on a spinlock.

I left it for almost an hour whilst I did something else.

I believe the spinlock code on my system, SPARCLinux, is OK
from running the s_lock_test, see below.

Any ideas what's happening?

Keith.
