Hi Urjit, Unfortunately, I can't reach the computers with problem when running the client software, I don't even know where they are.
I just checked the server, and the stuck process is still there, running more than two weeks: 20743 jdu ./reg_mpt 14-18:43:57 #ls /proc/20743/fd/ -l total 4 lr-x------ 1 jdu jdu 64 2008-08-05 08:00 0 -> /dev/null l-wx------ 1 jdu jdu 64 2008-08-05 08:00 1 -> /home/..... l-wx------ 1 jdu jdu 64 2008-08-05 08:00 2 -> /home/..... lrwx------ 1 jdu jdu 64 2008-08-05 08:00 4 -> socket:[210395564] After # lsof | grep 20743 reg_mpt 20743 jdu 0r CHR 1,3 861 /dev/null reg_mpt 20743 jdu 1w REG 9,3 32814994 6784 /home/..... reg_mpt 20743 jdu 2w REG 9,3 32814994 6784 /home/..... reg_mpt 20743 jdu 4u IPv4 210395564 TCP xxx.xxx.net:17117->2x.9x.x0.x0.xxx.xxx.xxx.xxx:19048 (ESTABLISHED) I don't think that socket connection is still there, but why the Linux is not aware of the broken socket connection?
