Random Server Issues

Hello,

We use WingFTP running in multiple environments, the majority running fine on Windows servers, but we are running into an odd issue on our CentOS 7 Apache web server.

We have 6 domains setup here, and two of these domains get the bulk of their use through uploading and downloading custom files that get generated by software they've made. This is all happening in the background over standard port 21 connections.

Randomly, for these two domains only, they will stop allowing port 21 connections, but continue to work through the web portal. A server restart gets them working immediately, and the domain logs show nothing after a certain point.

Any assistance would be helpful, if any additional information is needed, let me know.

Any update on this? I'm finding something similar, except on port 22 (SSH). This happens a few times per day.

Please upgrade to the latest version 6.0.5, because the new version updated the SFTP library "libssh" and also made a few improvements.

To increase the number of available sockets on Linux, you can check out this article:

It appears that 6.0.5 alone does not fix the issue. I will try adjusting the sockets as advised in this post...

When did you download the version 6.0.5?

I downloaded it after your post on March 18th. Additionally I followed the URL on open files and applied changes, that did not fix the issue either.

Has anything changed since March 18th (the last time I downloaded it)?
