Not being a "c" developer, perhaps I am totally wrong, and therefore beg for your understanding ... ;) Is it normal for the * executable to be increasing in memory size ? I've noticed when using "top" that the * executable starts life like PID USER PRI NI SIZE RSS SHARE STAT %CPU %MEM TIME CPU COMMAND 530 root 16 0 9496 9432 4648 S 0.5 1.8 0:31 0 asterisk however, after a couple of days, the "size" column indicates "60MB", when there are no channels and no calls active. Is that normal ? We use ISDN pri to the outside world, and SIP (Cisco 7960) internally, with Agentcallbacklogin for queues. CVS head as of the start of the month. Julian.
