I hate mailing list threads that post a problem but not the solution, so I thought I would write back to say that the issue appears to have been some strangness with the Oracle libraries. Looking at our snapshotted volume, the libraries had not changed since installing about 2 months ago. However, for reasons that are still unclear, any attempt to connect to Oracle from that box looked at the sqlnet.ora file and then went into a strange polling state that consumed all available CPU. After getting some hint of this from stracing the hung mongrel process, we were able to reproduce the same problem using just sqlplus. So this was NOT a mongrel nor a rails issue. Perhaps even more mystriously, rebooting the server (a Xen VM running RHEL 5) fixed the problem. Thanks to the folks here and on the mongrel IRC room for all their suggestions on how to track this down.
