We're running UD so I can't help you on the uv stuff but a couple of general RH points that effect U2 sites... 1. If you are using telnet clients to connect you may need to up the number of telnet connections allowed.. Include the following in /etc/xinetd.d/telnet instances = UNLIMITED Although you can set instances to a sensible value - by default this is 60. 2. Watch your max open files across the system. You can see what this is with cat /proc/sys/fs/file-nr This will give you 3 numbers (e.g.) 1000 150 8192 The 1st and 3rd are the critical - if the 1st gets close to the third you will get file open errors. The 1st is roughly how many files have been opened at any one point and the 3rd is the max allowed for the entire system. You will also get the 3rd number if you do cat /proc/sys/fs/file-max Add a line like fs.file-max = 65536 to /etc/sysctl.conf and then run sysctl -p to update on the fly. Note for tweaking you can just do something like echo 65536 > /proc/sys/fs/file-max but this won't survive a reboot.
