i did some analyse to the problem, as a customer of mine has it also. i found out that it looped at read_data, which calls sys_read in system.c. it happened while the system had high cpu usage anyway (mostly tcp/ip traffic). conclusion: high cpu usage and a client connects to samba, samba opens a new PID, but the PID gets in a wait status due to the high cpu usage. now sys_read loops while there is no data and EAGIAN. if another client wants to connect, a new PID is created and also this PID stays in the loop. and so forth with every new connection. samba ends the PID after around 5 minutes, but because there are more then one it will never finish with ending all of them and cpu stays at 100% cpu.
