@Adamsin Nobody can ping the servers, because our servers block ping requests by default. Fortunately, servers don’t need to be pingable to handle FTP traffic.
@anirudhvprabhu Yes, the issue still persists. Hence the system issue notice. The annoying part is that this issue only seems to occur sometimes, but not all the time. I think it started last Sunday, and there are brief windows where this is an issue.
Also, there are no indications that any files are getting lost. And the last thing we need right now is everyone trying to connect to FTP to backup all their files, because FTP server capacity is the key issue here.
We had a fix which looked good for a few days, and then new problems were starting to arise. We’re having trouble getting grip on this issue, which is why it’s taking so long. I don’t know whether this is actually the same issue or another issue with the same symptoms.
As far as I can tell, this is a load issue on the storage cluster, which could also explain the poor transfer space when you are able to connect to the servers.
This issue is hard to detect, debug and fix, which is why it’s taking so long.
