unresponsive mlnet
on my server i like to use some p2p software. my favourite network is the edonkey/emule/overnet network, and since i use mac, i am stuck with the mldonkey client. this works fairly well for me, except that there is a bug which will crash the program (see forum thread on macdk.com), and it becomes unresponsive.
it seams though, that the programm keeps running and downloading even after crashing, but only for a limited time. after this, it will stop downloading.
i did some statistics (see the network activity log entry) to see what median upload and download duration i have:
these stats have been done with mldonkey ver2.5.22 without modifying the file descriptor count. i will redo some statistics with increased file descriptor count.
in the mean time, when testing the not-crashed duration, i add following lines to my crontab:
this causes mlnet to be shut down an restarted 3 times a day automatically. for more information on crontab see this blog entry.

in the mean time, when testing the not-crashed duration, i add following lines to my crontab:
# kill & restart mlnet
