What version is this? Hm, so the startup process finds the consistent point (which signals postmaster so that line 23612/3 says "ready to accept read-only conns") and immediately dies because of the invalid memory alloc error. I suppose that error must be while trying to process some xlog record, but without a xlog address it's difficult to say anything. I suppose you could try to pg_xlogdump WAL starting at the last known good address 3/8811DFF0 but I wouldn't know what to look for. One strange thing is that xlog replay sets up an error context, so you would have had a line like "xlog redo HEAP" etc, but there's nothing here. So maybe the allocation is not exactly in xlog replay, but something different. We'd need to see a backtrace in order to see what. Since this occurs in the startup process, probably the easiest way is to patch the source to turn that error into PANIC, then re-run and examine the resulting core file. -- Álvaro Herrera http://www.2ndQuadrant.com/ PostgreSQL Development, 24x7 Support, Remote DBA, Training & Services -- Sent via pgsql-general mailing list (pgsql-general@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-general
