Summary: [patch] Huge memory leak because memory of channel
cdr struct is never returned
Description:
After two days of stress testing by making lots of calls across sip and
dahdi channels the asterisk process memory reached dizzy values: VSZ=3,2GB,
RSS=1,6GB before asterisk stucked completely (even the RAM of our server
(2GB) is finite ;-) ).
Actually this problem is not a question of load, but appears for each
single call.
Using valgrind the reason for that was quickly found: The memory of the
channel cdr struct (chan->cdr) is never returned, not for sip, not for
dahdi channels, when a channel is cleared.
Reproduce:
a.f.a.p. default configuration (modules.conf, etc.)
Make lots of calls and see ps's VSZ and RSS values.
Interested in a patch ? Or is someone revise this anyway?
