The problem is that sometimes the -current system becomes unable to fork *any* new processes, and even suspending or trying to kill the bfbtester process does not work. The rest of the system performance is fine (I can use existing processes with no noticeable CPU latency): so it does not appear to be a resource starvation condition. rot13# ls [hangs] load: 0.00 cmd: csh 22888 [vmmapw] 0.00u 0.00s 0% 1160k This process now cannot be interrupted by signals. => /usr/sbin/sendmail * Single argument testing ^Z Suspended [hang] load: 0.00 cmd: tcsh 8403 [inode] 0.01u 0.00s 0% 1076k Any ideas?
