The machine is acting as a gateway between two networks. Apparently every so often (quite frequently) all activity on the machine freezes for 3-4 seconds and then resumes. Or rather, all network activity; no one is actually working on the console so I don't know whether this applies to non-network activity as well. I asked him to check the load, free memory, etc, to try to determine whether it is simply caused by bus-mastering disk activity; however, it seems the load is not very high and there is no obvious cause related to disk I/O. Has anyone experienced this? Is it perhaps related to the 3C509 driver? Any suggestions would be appreciated.
