Using a quad core 1.86GHz Xeon CPU here, running Asterisk 1.4.2. Noticed the following: Cpu(s): 4.3% us, 95.4% sy, 0.0% ni, 0.2% id, 0.0% wa, 0.0% hi, 0.0% si 30908 asterisk 18 0 188m 10m 5152 S 400 0.3 51051:13 asterisk Asterisk is eating up all the cores running the CPU at 400%. Is there something broken in 1.4.2 that needs to be addressed? Any suggestions? There's currently zero calls going on. - sf
