We are using Serv-U FTP 15.1.3.3 to act as a gateway to an image library. Our system uses one shared account to access many tifs and jpg files. They are small in size and 99% of the time it works just fine. We typically have about 1 transfer happening every 10 seconds or so during business hours.
For the past 3 weeks we have had a condition where the serve esentially freezes up for about 10 minutes. The verbose lo I turned on stops recording and then what happens is that a hundred plus users start queuine up so that when the server "wakes up" again it has so many requests at once that we hit the 100 user license limit and takes a while to catch up. These 10 minute outages are essentially blank time in the logs and we don't know where to go from here.
Our workload is about the same each day and the requests come from an app so it's not like the user can do different requsts. Dozens of hours have been spent to find that the ServU server is doing this or befing affected by something to do it.
Is this a bug in ServU or can you help me diagnose this for our company?
Thank you so much!
