Description Mathias Retzlaff 2004-11-17 15:35:46 UTC
Description of problem:
On this machine there is running a server written in Java.

It is running stable for about one or two days and then it hangs. Our 
research revealed, that it called a native method, that tried to read 
from a file on the harddisk (it's an SCSI device) and that method 
does not return. (We observed a case where it returned with 
successful reading after about 5 minutes.)

It is everytime a different file and the file can be read without 
problems after restarting the server.

There are some strange messages in the syslog:
