We are experiencing a tcp connection problem on our server lately. This means that we cant establish a tcp connection from the server to any host/service untill the server has been restarted.
The server is a servicing as a webserver with Apache/2.0.59 (Win32) PHP/4.4.6.
Then suddendly for some reason, after some days the server goes into an "error state" where it isnt possible to establish TCP connections from the server, until a restart.
I then checked if was even possible to telnet to the database or any other remote TCP service. Telnet returned error:" Connecting to <servername/ip> ...Could not open connection to the host, on port <TCP service number>: connect failed"
After the restart, the server works fine again for a couple of days.
I have checked our firewall, as this is between the webserver and the database. No errors
Windows event log doesnt give me any errors either.
As I cant establish a tcp connection from command prompt, I assume this is OS and not Apache related.
Have any been experiencing similar, or have any suggestions how to solve this?
