Smth strange with server

[Roman Veretelnikov]

Hello,

I cannot login. ssh client hangs after entering login/password.
I use webmin to view system logs and see following in the
/var/log/messages

Also there are many bash processes in "Running Processes"
All other services work fine including httpd, mysql, xmail, syslog,
etc...

Kernel 2.4.22-1.2174.nptlsmp. System is P4 with HT. Is fedora's kernel
still unstable on SMP machines? What can I do to solve this problem?

P.S. Sorry for my english :-)
