[Users] OpenSER not working after running for several days

Hi Richard, This is a very interesting discussion. However I don't think our situations are similar. Just to make it clear, in your case, did OpenSER slow down or stop working at all? Was it something that happened gradually? In my case, it runs fine for several days. There are no delays, no slowing down of any kind. Then suddenly it stops responding. There is no script change, nothing at all. Actually most of the times it happened during the night when there is nobody around "playing" with DNS, network settings etc. So what could be causing this? Can I set up some sort of logging that will help find the cause of this? I have no clue what kind of information I should be logging. Most of my troubleshooting is done with ngrep. I could redirect this to a log file, but with the volume of traffic that we have, a few hours would be enough to fill the disk. thank you for any help George Disclaimer The information in this e-mail and any attachments is confidential.
