Hi all :) FreeRADIUS 2.1.7 CentOS 5.2 I am not too sure where to start here so I will describe the symptoms first: I have 2 freeradius servers that both receive accounting requests, and proxy these requests to each other, as well as log these requests to a detail file. I have noticed now that while server A is processing the detail-combined file and proxying the requests to server B, server B will fail to get a lock on its detail file, and the request will fail. When this happens it is not passing anything back to server A, and server A does not seem to be timing out the request, so it stops processing the detail-combined file and just sits there. A bit more in depth, server B is still running FR 1.1.6. I am in the process of updating to 2.1.7 but am being delayed due to outdated OS, so am moving this lot to a new server. The lock fail is occurring when server B tries to get a lock on the detail-combined file, so it is very likely that I have had the proxying setup incorrectly here all along, but since it is 1.1.6 I do not expect help here... What I would like to try figure out is how to get server A (2.1.7) to time out a proxy request and retry it... Any pointers to sections/docs would be great as always, Thanks a mill! Patric
