We've been noticing a strange problem with our MAX 4000. Every few minutes (usually about every two minutes) the response time of the MAX increases for a short period (up to about 15 seconds). For example, when pinging the MAX from a host on the same network, the response time is usually about 1-2 ms, but about once every two minutes that response time can jump to several hundred milliseconds in the worst case. This problem also affects packets going through the MAX - to a customer's P50, for example. We ran tcpdump, but we didn't notice any unusual traffic when the MAX's response time increased. We also couldn't correlate any activity on the MAX (e.g. incoming/outgoing calls, etc.) with the increased response time. This problem doesn't occur when pinging other hosts on the network, and we wouldn't have noticed it with the MAX if it hadn't been for a customer who noticed this problem when playing Quake across his ISDN connection. Apparently exactly once every two minutes he's seeing a significant lag and even some packet loss. And apparently this problem had never occurred before until it began sometime during the last few weeks. The MAX is running 5.0Ap27 (tik.m40) now, but the problem was also happening with 5.0Ap13. I know this is probably very little info to go on, but does anyone have any ideas on what might be causing this or has anyone else experienced something like this?
