Woke up this morning to find cameras were not being proxied (to zoneminder and our CCTV monitor in the front room in our case). Only one single error in the logs marking the point it stopped working. Might be an issue with the latest version I have been running an older version with the same config for a long while without issue. I just upgraded to the latest version 128 hours before. If it happens again I will try and capture more information. I panic restarted the service this morning before thinking about testing what response (if any) was being given on the RTSP port.

@lucien-kejl seems to be a TCP/network issue not literal filesystem files.

Would like to take this opportunity to thank the author(s) of this software. It saves my poor little server so much CPU compared to any solutions I had before.

Hello, the OS is responsible for limiting the number of opened file descriptors, the server can't do anything about it. Please tune the OS to increase the maximum number of file descriptors, there are plenty of tutorials about it.

@mwvent I think it is the problem of TCP/network ,but I start the server, it will happen after some hours . Have you come across this problem again？Do you solve it ?
