I've about 1k users connected, and after some days (or weeks) i run into on the following issue: PID USERNAME THR PRI NICE SIZE RES STATE C TIME WCPU COMM= AND 55180 root 2 52 0 338M 85204K uwrlck 2 2:28 0.00% mp= d5 The process stuck on uwrlck state. Do you have any idea? My last try was set a cpu affinity on process. After this it's running 9 da= ys and counting. But i gonna need more days to make sure it really worked. Anyway, how have you made the test? how many users connected? Thanks. --=20 You are receiving this mail because: You are on the CC list for the bug.=
