DFSR Service Crashing Frequently & Erroneous Sharing Violations
We've got two 2008 R2 servers with DFS running and one replicated folder. I've been having trouble with one of them. The DFSR service seems to be crashing as often as every 20 mintues at which point it begins to do lots of read/write I/O presumably to rebuild the database. Some times it might go a few hours without crashing. In any case, it has died 50 times in the last four days. On the other system, it hasn't crashed once in days.
I also (perhaps unrelated, perhaps not) have received thousands of sharing violation errors. They don't appear to go away, and any time I manually inspect a file reported as a sharing violation, it has always been replicated already. I have to clear the event log to get the violations to clear out of the health reports.
Are there any common causes for this? Is there anything I can try which might alleviate the problem without rebuilding the box entirely?
Thank you for your time.
Addition:
Faulting modules always appear to be DFSRs.exe or ntdll.dll.

1. Do you have anti-virus on this box? if so, try disabling it for a while.
2. When the sharing violation occurs, run Process Explorer to reveal what other processes have this file open.
3. If the crash persists, run adplus.vbs in crash mode (from Windows Debugging Tools). It will generate a dump of DFSRs.exe. Publish this dump at your Live Skydrive and let me know. I'll analyze it for you.

No anti-virus on this machine currently. I do intend to take you up on this offer. I've been waiting for a good moment to re-instate my replication group (I'd removed it temporarily since the service was being so problematic). The last time I re-created the group, it helpfully decided to start deleting all of the files on the first server instead of replicating them to the second, so I have to stop all file transactions and make a backup first.
I'll try to post the log for you in a few days.
