>Description:
The machine is a web server hosting around 50 virtual hosts. The problem happens randomly (i.e. no specific pattern) but I suspect that it is caused by transferring large files (from a previous report, that is still open). The messages in dmesg are as follows:

Then, the machine becomes unreachable.
