Hi everyone. The following error appeared in our log yesterday: 2009-11-19 13:39:40 PST:10.211.97.171(63815):[25668]: PANIC: stuck spinlock (0x2aac3678b0e0) detected at dynahash.c:876 Followed by: 2009-11-19 13:44:24 PST::@:[1381]: LOG: server process (PID 25668) was terminated by signal 6: Aborted 2009-11-19 13:44:24 PST::@:[1381]: LOG: terminating any other active server processes Followed by: 2009-11-19 13:44:24 PST:10.211.1.171(8016):[29736]: WARNING: terminating connection because of crash of another server process 2009-11-19 13:44:24 PST:10.211.1.171(8016):[29736]: DETAIL: The postmaster has commanded this server process to roll back the current transaction and exit, because another server process exited abnormally and possibly corrupted shared memory.

Finally: 2009-11-19 13:47:15 PST::@:[223331]: LOG: autovacuum launcher started 2009-11-19 13:47:15 PST::@:[1381]: LOG: database system is ready to accept connections The system was under a good amount of load: approximately 80 connections, each generating large numbers of batched inserts (using JDBC). This includes the one that crashed. Once the database re-initialized, everything went back to normal. Is this due to a bug in PostgreSQL? Is there anything we can do about it? :-) We are running PostgreSQL 8.3.8 (64-bit) on a dedicated Fedora Core 8 machine, in Amazon EC2. This was using an "extra-large" instance, which means 4 Xeon cores (2.66 GHz) and 15.5 GB of memory.
