Since there are several of us experiencing what looks to be the same sort of deadlock issue, I beseech you not to give up ... right now, all we've been able to get to the developers is virtually useless information (vmstat and such shows the problem, but it doesn't allow developers to identify the problem) ... Is this a problem that you can easily recreate, even on a non-production machine? In my case, I have one machine fully configured for debugging, but, of course, since re-configuring it, it hasn't exhibited the problem ... if most of us get our machines configured properly to give useful information to the developers to debug this, the faster it will get fixed ... My experience with most of the developers is that if you can get into DDB and give them 'internal traces' of the code, bugs tend to get fixed very quickly ... vmstat/ps give "external views", more summaries then anything ... its the details "under the hood" that they need ... its not much different then your auto-mechanic ... try telling him there is a 'knocking under the hood, please tell me how to fix it, but you can't have my car', and he'll brush you off ... give him 30 minutes under the hood, and not only will he have identified it, but he'll probably fix it too ... ---- Marc G.
